Motor Bushing Carbon Steel Sleeve Bearing with Oil Grooves for Power Tool Motors

Product Description:

Qimao Metal Manufacturer’s Motor Bushing Carbon Steel Sleeve Bearing with Oil Grooves for Power Tool Motors on the outside. It’s a simple part, but how it’s made matters.

Three grooves total – one running vertical and two going around the circumference. They hold oil against the housing wall, and as the shaft turns, that oil works its way into the running clearance. Keeps metal off metal.

We use carbon steel because it stands up to the start-stop cycles and vibration you get in power tools. The bore gets burnished after machining, which knocks down the rough spots and gives it a better surface to run against.

Press it into the motor housing, drop in the shaft, add grease to the grooves before assembly. That’s pretty much how it works. The grooves keep lubrication distributed so the bushing lasts.

Products Details:

This Motor Bushing Carbon Steel Sleeve Bearing with Oil Grooves for Power Tool Motors has three oil grooves on the outside – one running lengthwise and two around the circumference. They don’t break through the wall, just deep enough to hold oil against the housing.

The bore gets ground after the grooves are cut, so any distortion from that operation gets cleaned up in the final grind. Standard ground finish, not polished.

Hardness runs between 20 and 30 HRC. Soft enough not to score the shaft, hard enough to resist wear.

OD is ground a few microns over the housing bore for a proper press-fit. ID leaves a couple of hundredths clearance for the shaft to spin. Straightness gets checked on every piece.

Product Feature:

• The Motor Bushing Carbon Steel Sleeve Bearing with Oil Grooves for Power Tool Motors with three oil grooves on the outside – one straight down the length, two circling around. Hold oil against the housing wall.

• Grooves aren’t cut all the way through. Keeps the bushing solid.

• Bore gets ground after grooving. Cleans up any distortion from the cutting operation.

• Standard ground surface finish. No mirror polish because it doesn’t add anything useful here.

• Hardness runs 20 to 30 HRC. Won’t scratch the shaft, won’t wear out fast either.

• OD ground for a proper press-fit. ID leaves a bit of clearance so the shaft spins free.

• Every piece gets checked for straightness. A bent bushing makes the tool shake, so we don’t let those through.

Product Application:

• Handheld drills and impact drivers. The Motor Bushing Carbon Steel Sleeve Bearing with Oil Grooves for Power Tool Motors runs hard, you’re pushing into the work, dust and heat build up. This bushing keeps the shaft supported through all that.

• Angle grinders and polishers. High speed, heavy loads, and they get run for hours sometimes. The oil grooves make a real difference here – they keep lubrication where it needs to be.

• Circular saws. Start-stop cycles, sudden torque reversals when the blade catches. That kind of abuse kills plain bushings fast. These hold up better.

• Repair shops that rebuild power tool motors. A customer brings in a tool that’s seized or noisy, and you can bet the bushing is part of the problem. Ours go in as a direct replacement.

• OEM assembly lines. They run thousands of motors a day and need components that fit right the first time, no fiddling around. That’s what we deliver.

• Maintenance departments in workshops and job sites. Keeping existing tools running is cheaper than buying new ones, and replacing a worn bushing gets a tool back in service quick.
