We replace BFT gate hinges and rollers in San Antonio for $165 – $340 installed, depending on your gate’s size, weight, and which specific BFT series you own. Most hinge and roller swaps on BFT swing and slide gates take under two hours, and our service trucks carry the common BFT-compatible hardware so we’re usually done same day. The typical discovery moment goes like this: the gate starts making a groan when it moves, then one morning it drags against the ground or stops mid-travel, and you realize what used to glide now grinds. That sound is metal-on-metal wear, and it’s the part telling you it’s done.
Here’s what San Antonio homeowners need to know before paying for this repair, what actually fails on BFT hardware, and what a fair installed price looks like.
Which BFT Models This Applies To
BFT builds gate operators under several sub-brands, and the hinge and roller hardware varies by series. The most common ones we service in San Antonio are the Deimos slide gate series, the Icaro and Sub swing gate lines, and the Rigel and Phobos hydraulic and electromechanical operators paired with them. Each has different roller wheel diameters and hinge pin specs, so a wheel that fits a Deimos slide won’t necessarily ride right on a Rigel track.
Two ways to identify what you need: check the metal tag on the operator chassis (it carries the model prefix and serial), or measure the existing roller. BFT-compatible slide rollers typically run 40mm, 50mm, or 60mm wheel diameters with a bearing bore that’s either 12mm or 20mm, depending on the gate’s weight rating. Swing gate hinges on BFT systems are usually adjustable heavy-duty pedestal hinges with grease fittings; the bolt spacing matters more than people think, and getting it wrong means redrilling the post.
We install OEM BFT parts when the gate is still under warranty or the customer prefers factory hardware. For everything else, we use aftermarket equivalents that match BFT’s load ratings and dimensions, sourced from industrial gate hardware suppliers. The aftermarket option saves roughly 25 – 40% on parts cost with no meaningful difference in lifespan, provided the bolt pattern and wheel diameter match exactly.
Calder Gate Repair San Antonio is an independent gate repair company and not affiliated with BFT. We’re factory-familiar with BFT equipment because it’s one of the nine major brands our technicians train on: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule.

Signs Your BFT Hinge & Roller Replacement Is Failing
- The gate drops when it finishes opening or closing. This usually means the hinge pins have worn oversize or the roller wheel has flat-spotted, leaving the gate unsupported at full travel. In San Antonio’s dry, dusty conditions, grit works into the bearing and accelerates this by months.
- A grinding or squealing noise that changes with speed. If the noise comes from the lower edge of a slide gate, that’s a roller bearing that’s lost its grease and is running dry. BFT slide gates are heavy, and a seized roller can actually stall the motor.
- The gate scrapes the driveway or concrete pad. Flat-spotted roller wheels, sagging hinge mounts, or a bent hinge plate all drop the gate’s clearance. You’ll see fresh metal shavings or a scored line on the concrete.
- Visible play when you push the gate by hand at the hinge point. Swing gates should have almost no lateral wobble at the hinge. If the leaf moves a quarter inch or more when you push it, the hinge bushings are done and the gate will bind.
- The operator labors or trips its internal overcurrent protection. When the gate hardware can’t roll or swing freely, the BFT operator draws more amperage. That premature overload cycling shortens the motor and board life, so it’s cheaper to fix the mechanical problem before it becomes an electrical one.

AfterReplacement Cost & What’s Included
In San Antonio, expect to pay $165 – $340 installed for BFT hinge and roller replacement. That includes the parts, labor, alignment, and a load test on the operator. The spread comes from a few variables:
- Slide gate roller replacement: $165 – $220 for one or two rollers on a standard single-family gate. Wheels are cheap; the labor is in removing the gate weight off the bad roller, pressing the new wheel, and re-leveling the track path.
- Swing gate hinge replacement (one leaf, two hinges): $240 – $340. These are the heavy-duty pedestal hinges, and the job includes unweighting the leaf, replacing both hinge pins or full hinge bodies, and realigning the gate so the operator’s limit settings stay accurate.
- Track and guide adjustments along with the roller: add $40 – $60 if the track has shifted and needs re-anchoring.
Every quote is a written, line-item price agreed before we touch a bolt, and the number on the invoice matches the number on the quote. The 365-Day Done Right Promise applies to this repair in full: if the replacement hinge or roller fails within a year, we come back at no charge. No exceptions, no fine print.
DIY or Call Us?
There’s a small amount an owner can safely check. You can look for a scored line on the driveway, listen for the grind, and check the operator for error codes. You can even unplug the operator and push the gate manually to feel for resistance. That diagnostic part is free and smart.
The swap itself is where it gets dangerous. A BFT slide gate can weigh 400 – 800 pounds, and a swing gate leaf is a huge lever arm. When a roller or hinge fails, the safe way to replace it involves jacking and supporting the gate, which is a two-person job with the right lifting equipment. Every year, people get pinned or crushed working under an unsupported gate. We’d rather see you call. Nico Alvarez puts it plainly: if the price isn’t in writing, it isn’t real, so you’ll have a texted quote before any work begins. Call (361) 314-4803 and we’ll send a real number, not a range.
FAQs
In San Antonio’s heat and caliche dust, expect 4 – 7 years from stock BFT rollers and hinges on a gate that cycles 8 – 12 times a day. Gates that sit in direct afternoon sun and never get a bearing greased wear faster, and gates that are out of alignment kill rollers in half that time.
Generally no. Once the wheel is flat-spotted or the bearing is loose, pressing a new bearing in a worn wheel doesn’t buy you much time, and the labor cost is nearly identical to a proper replacement. Call (361) 314-4803 and we’ll tell you honestly if yours is rebuildable or replacement-only.
Most BFT hinge or roller replacements on a residential gate take 60 – 90 minutes once the tech is on site. Swing gate hinge jobs with realignment run closer to two hours.
Yes. Our San Antonio service trucks carry common BFT-compatible roller diameters and hinge pin kits, so we complete most of these jobs on the first visit. We also keep parts on hand for LiftMaster, Mighty Mule, and Ghost Controls systems if your property has more than one opener brand.
