YBS-NCA 52 Polyurea Long‑Life Grease for High‑Speed Miniature Precision Bearings
Thanks to polyurea thickening technology, the grease possesses exceptional thermal‑oxidation stability, resisting coking and degradation under continuous high‑temperature operating conditions. It achieves low‑noise running effect for bearings, while maintaining good fluidity at low temperature down to ‑50℃. This product is mainly oriented to sealed small‑size bearings, supporting long‑term maintenance‑free lubrication. It is widely adopted in household appliances, power tools, small motors and industrial precision rotating parts as a reliable high‑speed lubrication solution.
Performance characteristics
Excellent high‑temperature oxidation resistance: Polyurea thickener resists thermal ageing, less carbon residue, long service life for continuous high‑temp operation
Broad temperature performance: Stable lubrication from ‑50 ℃ low temperature up to 150 ℃, suitable for cold‑hot alternating environments
Low‑noise running property: Smooth grease texture, optimized for miniature bearings, reduces running noise
- High‑speed adaptability: Matches high speed working condition of small rolling bearings, low heat generation
- Maintenance‑free long‑life performance: For sealed bearings, extend re‑lubrication interval or realize lifetime lubrication
- Good material compatibility: Compatible with most ferrous & non‑ferrous metals, good adaptability with many engineering plastics
