INA RLBSR71-100 Bearing 28mm x 23mm x 17.5mm RLBSR71-0100 for Textile Machinery
Product Overview
This INA RLBSR71-100/RLBSR71-0100 bearing (28mm × 23mm × 17.5mm) is a precision tensioner bearing tailored for textile machinery. Crafted from premium GCr15 bearing steel (HRC 60-65) with double-sided sealed structure, it resists textile fibers and dust, supports high-speed stable operation, and ensures reliable tension control for spinning, weaving and dyeing equipment.
Product Advantages
- Fiber-Proof Sealing: Double-sided seals block cotton lint and debris, preventing lubricant contamination in textile workshops.
- High-Speed Stability: Precision-ground raceways minimize friction, adapting to 20,000rpm high-speed operation of textile machinery.
- Durable Wear Resistance: GCr15 steel with heat treatment offers excellent hardness, withstanding continuous cyclic motion.
- Precise Tension Control: Optimized structure maintains stable belt tension, avoiding yarn breakage or uneven fabric.
- Easy Installation: Direct-fit design matches textile equipment mounting standards, enabling quick replacement.
Applicable Industries
- Spinning & weaving machinery manufacturing
- Textile printing & dyeing equipment assembly
- Non-woven fabric production lines
