5.Bearing: Single & Double Row Deep Groove Ball Bearing 2RZ&2Z with C3 clearance.
6.Seals: Grease retaining inner seal with Multi-stage Labyrinth and Retention Cap with Outboard Rubbing Flinger Seal.
7. Lubrication: Grease is Lithium soap type grease with Rust Inhibitors.
8. Welding: Mixed gas shielded arc welding end
9. Our roller saves on repair and maintenance costs of the conveyer belt due to the concentric design which decreases vibration.
Besides we can manufacture the rollers and idlers according to the buyers' requirements

The rollers/idlers are made from high precision welding pipes and seamless tubes, steel plates and the body of the roller/idler and the bearing are welded as an integrated one by extrusion and argon guarantee welding, which make the rollers/idlers low resistance coefficient, long lifetime. The seal of our rollers/idlers are labyrinth seal, which make the rollers/idlers fine waterproof and dustproof.
The concentric design of the roller/idler decreases vibration.
