1. High quality and Competitive price, 2. ISO9001: 2008 3. Material: Chrome steel and stainless steel 1. Certification: ISO9001: 2000 2. Model: IR 3. Inner ring have high precision, good price 4. To keep a normal operational backlash The inner ring of IR series is quenched and made with high precision. The dimensional tolerance and the geometric precision of the standard grade inner ring is in compliance with P0 grade. In using FHL needle roller bearings, the selection of FHL inner ring will enable the bearing to keep a normal operational backlash.
