Description: Bearing housing (mounted bearing unit / bearing support assembly) is key mechanical component deployed across corn gluten concentration dehydration equipment (belt filter press, screw press dehydrator, vacuum drum filter etc.), supporting diverse rotating rollers, auger shafts and rotary drums. It transmits shaft originated radial and axial loads onto equipment main frame; securing rotating components (roller / auger / drum) maintaining stable centre line position during rotary operation; lowering frictional resistance and suppressing vibration.
Bearing housing body: Square form cast iron / stainless steel support block with bottom mounting holes for fastening onto equipment frame.
Insert bearing: Rolling bearing pre assembled inside housing cavity; spherical outer ring geometry enabling self alignment function.
Bearing inner ring: Interference fit onto roller shaft; rotates synchronously with rotary shaft.
Sealing components: Dual side sealing rings / dust covers blocking moisture and dust ingress toward bearing cavity.
Grease fitting: Top mounted grease nipple for periodic bearing grease replenishment lubrication.
Set screw / locking sleeve: Secures bearing inner ring onto shaft journal preventing axial shaft displacement.
Oil cup / grease level indicator: For lubrication status visual inspection and grease top up.
Operates on rolling friction and radial support mechanical principle:
1. Support and positioning: Bearing housing is fixed onto equipment frame; insert bearing seats onto roller shaft end and supports roller assembly at design centre height.
2. Friction reduction: During roller rotation, rolling elements (balls / rollers) roll between inner and outer races; converting sliding friction into low loss rolling friction and lowering rotary resistance.
3. Load bearing capacity: Absorbs filter belt tension originated radial loads, material dead weight and limited magnitude axial loads.
4. Self alignment compensation: Spherical mating surface between insert bearing outer ring and housing inner bore automatically compensates minor installation mis alignment and roller deflection deformation.
5. Sealing and lubrication: Seals prevent moisture dust intrusion; periodic grease replenishment via grease fitting maintains favourable bearing lubrication state.
Food grade available construction: Stainless steel housing variant satisfies food processing workshop hygiene demands.
Reliable sealing performance: Double lip sealing ring plus dust cover assembly effectively blocks water and dust ingress.
Built in self alignment function: Insert bearing compensates installation deviation and roller deflection distortion.
Simple lubrication routine: Grease replenishment through top grease fitting; low maintenance workload.
Quick installation property: Complete pre assembled bearing housing unit can be directly bolted onto frame mount points.
High component interchangeability: Standard dimensional specification, easy spare part procurement.
Smooth stable operation: Low vibration low noise running behaviour; extends service life of rollers and filter belts.
