UE Series Insert Ball Bearings | Eccentric Locking Collar Insert Bearings

UE series insert ball bearings are single row spherical outer surface insert bearings fitted with eccentric locking collar. This bearing can be mounted into various pillow block bearing housings such as UEP housing, widely used as replacement bearing inserts for agricultural machinery, conveyor systems and packaging equipment. The eccentric collar design locks firmly on shaft without damage to shaft surface, ideal for unidirectional rotation working conditions.

Key Advantages of UE Insert Bearings

Eccentric Locking Collar

Eccentric collar self-tightens with shaft rotation, no set screw indentation on shaft surface, stable clamping force for continuous operation.

Self Aligning Spherical Outer Ring

Spherical outer diameter compensates minor shaft misalignment, reduces extra friction and prolong bearing service life.

Double Lip Seals & Pre Greased

Factory pre-lubricated with high temperature grease, double rubber seals block dust and moisture, ready for direct installation.

Replaceable Insert Design

Can be installed in multiple standard pillow block housings, convenient maintenance, only replace insert instead of whole bearing unit.

Product Description

UE insert ball bearing belongs to insert bearing family, different from UC series set screw locking insert bearings. UE bearing adopts eccentric locking collar mechanism. Rotate the eccentric collar along shaft rotation direction to clamp the inner ring tightly onto shaft. This locking method avoids shaft surface damage caused by set screw. UE insert bearing has spherical outer surface, matching with cast iron pillow block housing, it can compensate shaft misalignment during installation. Standard UE insert bearing is equipped with double rubber seals, pre-filled grease, suitable for medium load, unidirectional rotation, dusty working environment. Larger size UE213 and UE214 insert bearings are available upon request.

Frequently Asked Questions

Q1: What is the difference between UE insert bearing and UC insert bearing?

A1: UE insert bearing uses eccentric locking collar to lock shaft, no set screw to scratch shaft surface, suitable for unidirectional rotation. UC insert bearing uses two set screws on inner ring for locking, can work for bidirectional rotation.

Q2: Can UE insert bearing fit into UCP pillow block housing?

A2: Yes, UE insert bearing has spherical outer diameter, it can be installed into standard UEP / UCP / UCF pillow block housing as replacement insert bearing.

Q3: What working condition is UE series insert bearing suitable for?

A3: UE insert bearings are recommended for unidirectional rotation equipment, medium load and moderate vibration applications, like agricultural harvesters and conveyors. Not recommended for high speed or frequent reverse rotation equipment.

Q4: Are UE insert bearings pre greased and sealed?

A4: Standard UE insert bearings are factory pre-lubricated with high quality grease and fitted with double lip rubber seals to prevent dust and water splash.

Q5: What is your MOQ for UE series insert ball bearings?

A5: We support bulk wholesale and small trial order. Some standard UE models are in stock, we can discuss MOQ according to your target quantity.

Q6: Can UE212 insert bearing replace UC212 insert bearing?

A6: They share same outer dimension and bore size, so they can fit same housing. But locking structure differs. UE uses eccentric collar and fits unidirectional rotation, UC uses set screws for forward and reverse rotation.

Q7: Do you keep UE series insert bearings in stock?

A7: Most standard UE insert bearings UE201 through UE212 are stocked in our warehouse, ready for fast shipment. Larger UE213 and UE214 can be produced upon order.

Mounted bearings & pillow block bearings - UCP, UCF, UC series with housing, ready-to-use units for industrial machinery

Pillow Block Bearings, also known as housed bearing units, are pre-assembled units combining high-precision insert ball bearings with robust cast iron or stainless steel housings. Designed for easy installation, reliable operation and low maintenance, these units feature excellent self-aligning performance, effective sealing against dust and moisture, and strong load capacity, making them ideal for a wide range of industrial applications.

Core Advantages

Easy & Fast Installation: Pre-assembled units eliminate the need for separate bearing and housing installation, reducing on-site assembly time.
Self-Aligning Performance: Spherical outer diameter of insert bearings automatically compensates for shaft misalignment and mounting errors, ensuring smooth operation.
Superior Sealing: Multi-labyrinth seals effectively block dust, dirt and moisture, extending service life in harsh working environments.
Wide Compatibility: Available in various housing styles (pillow block, flange, take-up) and shaft sizes, suitable for metric and inch shafts.
Low Maintenance: Equipped with grease fittings for convenient relubrication, supporting long-term continuous operation.

Typical Industrial Applications

Widely used in conveyor systems, agricultural machinery, food processing equipment, fans, pumps, packaging machines, textile equipment, mining machinery, and general industrial transmission systems.
