BMT Bearings is a China insert bearings manufacturer specializing in the development and production of high precision, low noise and long-life bearing products. Insert bearings are the inner bearing unit of pillow block ball bearing units, manufactured for equipment requiring stable shaft support, reliable positioning, and protection against dust, moisture and vibration during operation.
Supplied in the UC200 series from UC201 to UC210, with bore diameters from 12 mm to 50 mm and dynamic load ratings from 12,800 N to 37,500 N, these bearings are widely used in agricultural bearings applications, belt conveyors, packaging machinery, food processing lines and general industrial bearings equipment.
Every insert bearing is built around three performance pillars — accurate raceway geometry, secure shaft locking and reliable sealing protection.
Made from high-carbon chromium bearing steel and processed through precision grinding procedures, the bearing raceways achieve consistent accuracy and surface quality. This design helps reduce friction, operating vibration and heat generation during continuous running conditions.
Different locking structures are available to match various shaft installation requirements. Set screw locking, eccentric locking collar and adapter sleeve locking methods help maintain secure shaft positioning and improve operational stability. Adapter sleeves can be supplied as a matching accessory — see adapter sleeves.
The reinforced sealing structure helps reduce dust ingress, moisture penetration and fine particle contamination. Controlled grease filling improves lubricant retention and supports longer maintenance intervals in demanding environments.
Suitable for agricultural equipment, conveyor systems, packaging machinery, food processing equipment, ventilation systems and other applications requiring dependable shaft support. Matched housings are available under pillow block housing.
BMT Bearings provides standard UC200 models as well as customized insert bearings, including special dimensions, internal clearance adjustment, enhanced sealing structures, stainless steel components (see special material bearings), laser logo marking and OEM packaging.
Send us your drawing, shaft diameter and application details — our engineers will reply with a suitable model and wholesale quotation.
Standard set screw locking models with metric bore sizes. Eccentric locking collar and adapter sleeve versions are available on request.

Eight controlled production stages from raw material to finished insert bearing.
Raw bearing steel is inspected before production to ensure material consistency and a reliable performance foundation.
Components are forged and turned to achieve the required dimensions and prepare for precision machining.
Heat treatment improves material strength and wear resistance for stable long-term operation.
Precision grinding improves raceway accuracy and surface finish, reducing friction for smoother rotation.
Parts are cleaned before assembly to remove processing residues and maintain proper operating conditions.
Automatic assembly lines maintain consistent assembly accuracy and improve production stability.
Controlled grease filling improves lubricant retention and supports reliable operation in different conditions.
Finished bearings undergo final inspection to verify dimensional accuracy, rotation and quality consistency.
Routine inspection points that keep insert bearing quality consistent from batch to batch.
Non-standard insert bearings developed for specific equipment structures and operating environments.
Customized dimensions can be developed for equipment requiring specific installation sizes or structural requirements.
Internal clearance adjustments can be provided according to different load conditions, operating speeds and environments.
Customized sealing designs are available for applications needing extra protection against dust, moisture and contamination.
Stainless steel components can be selected for operating environments requiring additional corrosion resistance.
Laser logo marking and OEM packaging options are available according to product requirements.
Share drawings, samples or target specifications — we will confirm feasibility and lead time.
Four factors determine the correct model, locking method and sealing configuration.
The bearing size should match the shaft diameter to ensure proper installation and reliable shaft support — for example UC205 for a 25 mm shaft or UC208 for a 40 mm shaft.
The suitable locking structure should be selected according to shaft movement, vibration conditions and installation requirements — set screw, eccentric collar or adapter sleeve.
Dynamic and static load conditions should match the selected model specification to maintain stable bearing performance under continuous operation.
Dust, moisture, temperature and contamination levels should be considered when selecting sealing structures and bearing configurations.
Wherever a shaft needs stable support in a dusty, damp or continuously running environment.
Used in harvesters, seeders, fertilizer spreaders and grain handling systems where insert bearings must operate in dusty and outdoor environments.
Applied in belt conveyors, roller conveyors and bulk material transport equipment requiring continuous operation and stable shaft support.
Suitable for textile machinery, packaging equipment, food processing lines, ventilation systems and light automation equipment.
The reinforced sealing design makes these bearings suitable for applications exposed to moisture, dust and other challenging operating conditions.
