Product Details
Features
- Can be used without a lubricant supply in water, seawater, vapor or water splashes.
- Applicable within a wide temperature range.
- Resistant to intrusion of dust, sand or foreign bodies.
- Suitable for use with rotary and vibratory motion, and reciprocating and intermittent operation.
- Capable of operating at extremely low speeds compared with the solid- lubricant- embedded types, particularly with respect to minute motions.
- Capable of withstanding higher loads and supporting radial and thrust loads.
- Superior fretting resistance to that of solid- lubricant-embedded and ball bearing types.
Major Applications
General industrial machinery, food machinery and transport machinery
