Linear Hinge & Roller Replacement: The Simi Valley Owner’s Guide
We stock and install Linear-compatible gate hinges and rollers in Simi Valley, with most single-gate replacements running between $145 and $285 installed, including the parts, the labor, and a written record of what went on your gate. If you’re hearing a grinding sound when the gate moves, or the gate sags on one end and scrapes the driveway, a worn hinge or roller is the likely cause, and we can usually have the new parts on your gate the same day we diagnose it. The most common discovery is a gate that’s started dragging a groove into the concrete, with the telltale shriek of a roller that seized months ago.
Which Linear Models This Applies To
Linear gates come in a few distinct series, and the hinge and roller fitment changes between them. The Linear LRA series (the classic chain-driven residential slide gates) takes a specific 4-inch steel roller with a sealed bearing, while the heavier LRA-DT and SlideS series typically use a 5-inch roller rated for more weight. Linear swing gates, like the SWR series, use bolt-on steel hinges with a greaseable pivot, and those hinges are not interchangeable with the slide-gate rollers despite both falling under “hinge and roller” on a parts diagram.
Here’s the compatibility gotcha we see often in Simi Valley: a Linear gate built before 2016 may have imperial measurement hardware, while some 2017-and-later production runs switched to metric. The roller bolt diameter, not the roller wheel diameter, is what trips people up. A 1/2-inch bolt will not seat properly in a 12mm bracket, and if you force it, you get a wobble that wears the bracket hole into an oval. We check the bolt spec before quoting a part, not after.
On the OEM versus aftermarket question for Linear specifically: Linear-branded hinges and rollers are well made, but the aftermarket pieces we stock from DoorKing and select suppliers match the OEM spec and often have better bearing seals. For a homeowner, the aftermarket roller usually costs 20 to 30 percent less than the Linear-badged part and will outlast the original by a year or two in Simi Valley’s dry, dusty conditions. The saving isn’t worth chasing on the installation side, but it’s there on the parts side, and we’ll show you both prices before you choose.
Signs Your Linear Hinge & Roller Replacement Is Failing

- Scraping or grinding sound during travel. The roller bearing has seized or the wheel has worn flat on one side, and the gate is now dragging the roller across the track instead of rolling on it. This is the most common first symptom we see, and it’s usually the one homeowners wait too long to address.
- Gate sags or drops toward the free end. A worn hinge pin or a collapsed roller lets the gate settle, which misaligns the whole run. The gate then catches on the guide or the receiver, and the motor works against the extra drag until a limit switch or a gear strips.
- A noticeable groove appearing in the driveway or track area. That groove is dried concrete dust and steel filings being carved out a little more each day. By the time the groove is deep enough to catch a shoe, the roller wheel is usually gone completely, and you’re riding on the bare hub.
- Jerky or choppy movement, especially at the start of travel. A pitted or flat-spotted roller doesn’t roll smoothly, so the gate hesitates and lurches as the flat spot passes the track. This puts impact loads on the chain or belt, and on the operator gearbox.
- Visible rust bleeding from the hinge or roller area. Rust streaks mean the bearing or the hinge pin has been wet long enough to start corroding from the inside. In Simi Valley’s dry air this is less common than coastal climates, but irrigation overspray near a gate creates the same effect locally, and it eats rollers within two seasons.

AfterReplacement Cost & What’s Included
In Simi Valley, a single Linear gate roller replacement with the part and labor runs between $145 and $225 for slide gates. Hinge pairs on swing gates typically run $185 to $285 installed, depending on whether the old hinge welds or bolts need rework and whether the gate weight requires a heavier-duty hinge. If both the hinge and roller need replacement on the same gate, we quote the combined job and knock the diagnostic fee off the total, since we’re already there.
What drives the range is mostly the part spec, not mystery labor. A heavy-duty 5-inch sealed-bearing roller costs more than the standard 4-inch, and a greaseable swing hinge with a bronze bushing costs more than a sealed steel pivot. The labor on a roller swap is usually under an hour. The labor on a hinge replacement gets longer if the old hinge was welded rather than bolted, because the new one has to be cut, positioned, and re-welded at the correct height for the gate to hang square.
Everything is written before we start. You get the part number, the line-item price for the part, the labor amount, and the total, on paper, in your hand, before any tool leaves the truck. That’s Haven Standard Clause 1. The work carries the 365-Day Done Right Promise: if that roller or hinge gives you trouble within a year, we come back and make it right at no charge.
DIY or Call Us?

There are things an owner can check safely. You can look at the roller and see if the wheel still turns or if it’s frozen. You can check whether the hinge bolts are loose. You can take a photo of the part and email it to us, and we’ll tell you over the phone the likely spec and a rough price, with no obligation. What an owner should not do is unbolt a hinge or a roller while the gate is still supported only by the remaining hardware, because a couple hundred pounds of steel has no mercy for a hand in the wrong place. If the gate is motorized, the safest move is to leave the operator alone and let a tech handle anything that involves weight, tension, or electricity. Most Linear hinge and roller failures are mechanical, not electrical, but the weight of the gate itself is the hazard.

FAQs
In Simi Valley’s dry climate, a quality roller with a sealed bearing typically lasts 6 to 10 years on a properly aligned gate, and greasable swing hinges can go 10 to 15 before the pin wear becomes noticeable. The Simi Valley exception is gates near irrigation overspray, where water plus dust creates a grinding paste that can kill a roller in 2 to 3 years. If your gate is near sprinklers, keeping the spray off the track area extends the life more than anything else. Call (805) 516-0479 if you want us to look at yours and tell you what kind of lifespan is left on it.
For rollers, the honest answer is no; the bearing and the wheel are a sealed unit, and once the bearing is rough or the wheel is flat-spotted, the part is done. For hinges, a greasable hinge with a worn pin can sometimes be re-bushed or re-pinned if the hinge body is still solid, but on a Linear swing gate the cost of that machine work is rarely less than a new hinge. In our Simi Valley calls, we replace far more than we repair on this particular part. Call (805) 516-0479 and we’ll tell you which side your part falls on before you spend anything.
A single slide-gate roller replacement on a Linear gate usually takes under an hour once the gate is safely supported, including the inspection of the track and the other rollers. A swing-gate hinge replacement runs 2 to 3 hours when the old hinges are welded and need to be cut off and the new ones positioned, welded, and painted. We give you the time estimate in writing before we start, so you can plan the rest of your day around a real number, not a guess. Call (805) 516-0479 for a written estimate.
Yes. We keep the most common Linear roller specs, several hinge sizes, and compatible aftermarket equivalents stocked on the truck, so most Simi Valley replacements are same-day when you call us. For oddball sizes, we source the right part and usually have it on your gate within a couple of business days, and we’ll show you the spec difference before ordering anything. Call (805) 516-0479 and a live person will answer, any hour of the day or night.
