Bearings & Machined Parts

Housings · flanges · couplings · structures

Bearing housings, covers, flanges, couplings and machined structures. A bearing bore is not cut to nominal size: the bearing or journal is measured first and the bore set to it, with the clearance or interference written into the inspection record. Paired housings are bored at both ends in one set-up, so coaxiality comes from the fixture rather than a second alignment.

Typical use

  • Bearing housings and covers
  • Flanges, couplings and connectors
  • Frames and welded structures
  • Connecting parts for pumps, valves and hydraulics

Order paired housings together and we machine them together — done in separate batches, coaxiality is where they come apart.

    allowance for movement

  4. 04

    Stress relief

    before finishing

  5. 05

    Finish milling / boring

    paired parts in one set-up

  6. 06

    Drilling / tapping

    per hole layout

  7. 07

    Inspection

Circular forged steel coupling hub with central bore, a ring of bolt holes on the flange and a machined metallic finish.

Forged Flange Coupling Hubs

Forged flange coupling hubs in 42CrMo, 45# or Q345, CNC turned, milled and drilled, with quenching and tempering and custom bore, flange and coating options.

Steel friction torque limiter with slotted hub, stacked disc springs and locking nut on a machined flange body

Friction Torque Limiter (Adjustable Overload Clutch)

A mechanical overload clutch that slips when torque exceeds a preset limit and re-engages automatically, protecting motors, gearboxes and driven parts from jam damage.

Box-type bearing housing: vertical ribs, large top bearing bore ringed with bolt holes, side mounting ears.

Heavy-Duty Precision Bearing Housing

A machined bearing housing that supports large transmission shafts in metallurgy, mining and heavy drive equipment, with a ribbed box body and a precision-machined bearing seat.

Yellow multi-groove V-belt pulley, one-piece body, six web lightening holes and a machined centre bore with keyway

Heavy-Duty Cast Multi-Groove V-Belt Pulley

A cast pulley with multiple parallel V-grooves on a ribbed, lightened web. It drives belts on crushers, ball mills, fans, pumps and conveyors.

Gold-coloured drum gear coupling: keyed top hub, two bolted flange rings at mid-body, lower hub; split bolted construction

Drum Gear Coupling

Drum gear coupling built from two crowned external-tooth hubs joined by bolted internal-tooth flanges. It links two shafts, carries high torque and compensates radial, angular and axial misalignment.

One-piece fork: coaxial machined journals at both ends, U-shaped opening between arms, bolt and grease holes on the arms

Heavy-Duty Cardan Joint Fork

A one-piece forged fork for heavy-duty cardan shafts: two coaxial machined journals carry the bearings, and the U-shaped opening takes the cross journal and mating fork to form the joint.

One-piece ring-shaped coupling sleeve with internal spline teeth, external large gear teeth and machined stepped faces.

Internal-Spline Drum-Gear Coupling Sleeve

A half-coupling with an internal involute spline and external drum-shaped gear teeth. It connects shafts, meshes with a ring gear, transmits high torque and compensates misalignment.

Blue split bearing housing: bolted cap and base, large machined bore with ring, slotted mounting holes on the base flange

SN/SNU Split-Type Heavy-Duty Bearing Housing

Split cap-and-base bearing housing that supports rotating shafts and typically carries spherical roller bearings, with slotted base holes for alignment adjustment.
