Steel Flanged Sleeve Bearing – Hollow Design, OEM Bushing Manufacturer for Precision Machinery

Product Content:

As Steel Flanged Sleeve Bearing – Hollow Design, OEM Bushing Manufacturer for Precision Machinery from Qimao Metal Manufacturer is basically a sleeve with a shoulder at one end. The shoulder, or flange, takes the axial load. The sleeve takes the radial load. In our case it’s steel, hollow, and designed to sit on a shaft or inside a housing bore to guide and support rotating parts.  The flange makes installation simple, because you don’t have to second-guess the depth or worry about the bearing sliding through the hole.  We make these in carbon steel with black oxide finish, rolled surfaces, and consistent wall thickness throughout. It handles heavy loads, moderate speeds, and works in oily shop environments where alignment matters more than a fancy packaging. No PTFE lining, no plastic, no gimmicks. Just a plain bearing built for workholding, fixture plates, and industrial machinery that gets used every shift.

Technical Details:

The Steel Flanged Sleeve Bearing – Hollow Design, OEM Bushing Manufacturer for Precision Machinery matters on this part: the bore ID, the flange OD, the wall thickness, and the concentricity between the flange face and the shaft bore. If that runout is off by more than a few thou, your shaft doesn’t sit straight. We machine the flange face square to the bore axis, keep the wall thickness consistent so you don’t get high spots, and roll the surface finish so the shaft slides smooth without scoring.  Material is carbon steel, heat treated for hardness but not so brittle that it cracks under shock loading. Black oxide finish sheds oil and resists surface rust in normal shop humidity. We can also run phosphate or zinc plating if your spec calls for it. Sizes typically range from 10mm up to 50mm bore, but we’ll turn custom dimensions off your drawing. 

Core Advantages:

• Steel Flanged Sleeve Bearing – Hollow Design, OEM Bushing Manufacturer for Precision Machinery serves as a positive stop during installation, no guesswork on insertion depth 

• Hollow sleeve supports radial loads while the flange handles axial loads in one direction 

• Steel construction gives you strength that bronze or plastic can’t match in high-load applications

• Black oxide finish resists corrosion and holds lubrication on the running surface

• Rolled surface finish reduces friction and extends service life in sliding contact

Wide Usage:

• • Steel Flanged Sleeve Bearing – Hollow Design, OEM Bushing Manufacturer for Precision Machinery fixture plates and jigs – Drop one in and you’ve got a guide for locating pins or a shaft that slides straight. The flange sits flush, so you don’t measure insertion depth every time.

  • Machine tool assemblies – Shaft needs to rotate or slide without play. Steel sleeve gives you a consistent bearing surface, flange takes the thrust so the shaft stays put.

  • Workholding setups – The flange doubles as a shoulder stop. Clamp against it and you get repeatable depth without shimming or measuring.

  • Conveyors and packaging lines – Roller assemblies and guide rails. Steel handles constant cycling better than bronze, and the flange keeps the roller from shifting sideways.

  • Ag equipment – Harvesters, balers, spreaders. Dirt and dust kill fancy bearings. A plain steel sleeve just keeps going—no seals to blow out, no plastic to crack.

  • OEM production runs – Price matters. Reliability matters. These go in fast, no special tools, and run for thousands of cycles. Assembly shops keep ordering them.
