Bushing Bearings Manufacturing

Built for Reliable Industrial Supply

We manufacture and supply standard and made-to-order bearings for equipment manufacturers, engineering companies, distributors and industrial projects worldwide.

Our Factory

From Raw Material to Finished Bearing

Heat treatment line at the Bushing Bearings factory

Our factory produces rolling and plain bearings: deep groove and angular contact ball bearings, tapered, cylindrical, spherical and needle roller bearings, thrust bearings, insert bearings and housed units, plain bushings and precision balls. Production is organized around stable processes, controlled raceway geometry and dependable batch-to-batch clearance and noise levels.

Cold forming, thread rolling, machining, heat treatment, surface finishing, inspection and packing are coordinated to meet the requirements of each drawing, standard and application. Standard products and custom parts can be supplied across a wide range of sizes, materials and finishes.

01

Manufacturing

Cold heading, thread rolling, CNC machining, stamping and secondary operations for standard and custom hardware.

02

Materials

Carbon steel, alloy steel, stainless steel, brass, aluminum and other materials selected for the intended working environment.

03

Heat Treatment & Finishing

Mechanical properties and corrosion protection are controlled through suitable heat-treatment and surface-finishing processes.

04

Inspection

Dimensions, threads, hardness, mechanical properties, coating and appearance are checked according to the product specification.

Inside the plant

How your bearings are made

Every bearing we ship moves through the same six stages, in our own plant. The controls listed under each stage are the ones that decide whether a bearing holds its tolerance class, its clearance group and its noise grade — not marketing copy.

  1. Bearing ring blanks coming off the forging press
    01

    Forging & turning

    GCr15 bar and tube is cut, heated and forged into ring blanks, then turned to leave a uniform grinding allowance. Forging rather than machining from solid keeps the grain flow following the raceway, which is the surface that eventually fails.

    Blank dimensions and grinding stock checked at set-up and per shift.

  2. Bearing rings entering a continuous hardening furnace
    02

    Heat treatment

    Through-hardening brings GCr15 / 100Cr6 to 58–64 HRC; carburizing case-hardens 20CrMnTi where the section is heavy or the load is shock. Rings are then stabilized so they hold size in service rather than growing in the housing.

    Core and surface hardness per lot; retained austenite and dimensional stability to the ordered temperature class.

  3. Raceway grinding machine finishing a bearing inner ring
    03

    Raceway grinding

    Faces, bore, outer diameter and raceway are ground in sequence on separate machines. This is where the tolerance class is created: P0, P6, P5 or P4 is a grinding outcome, not a sorting outcome.

    Bore and outer diameter deviation, raceway roundness and face runout measured to ISO 492 on every setup.

  4. Superfinishing stones acting on a ground raceway
    04

    Honing & superfinishing

    The ground raceway is honed to remove the grinding lay and bring surface roughness down to a fraction of a micrometre. Raceway finish is what decides whether a lubricant film forms, and therefore what decides bearing life far more than the load rating alone.

    Surface roughness Ra and waviness measured per lot.

  5. Rings, balls and cages being matched on the assembly line
    05

    Assembly & clearance setting

    Rings, rolling elements and cage are matched, and the rolling elements are selected by size group to land the radial internal clearance in the group ordered — C2, CN, C3 or C4. Seals or shields are pressed in and the bearing is greased to the specified fill.

    Radial internal clearance gauged on every bearing to ISO 5753-1; grease weight verified.

  6. Finished bearings on a vibration test stand before packing
    06

    Noise, vibration & dispatch

    Every bearing is run on a vibration stand and graded Z1 / Z2 / Z3, because a bearing that is dimensionally perfect and noisy is a warranty return. It is then rust-preventive coated, wrapped and boxed to your part numbering, with the lot number travelling in the carton.

    Vibration level per bearing; lot traceability from carton back to the steel heat number.

Standards & Custom Parts

Made to the Specification Your Application Requires

We supply products to widely used ISO, DIN, ANSI/ASME and other industrial standards. When a standard item does not fit the application, our team can review drawings, samples and technical requirements for custom production.

Material grade, tolerance class, radial internal clearance, boundary dimensions, cage and seal type, noise and vibration level, marking, testing, packaging and documentation can be confirmed before production.

Dimensional inspection of finished bearings
  • Standard and non-standard bearings
  • Small-batch samples and volume production
  • Drawing and specification review
  • Export packing and organized batch identification
