Rubber Anti-Vibration Ring (RIS 2 Series)

Specifications

How to choose Bearing Accessories

Points to check when selecting, with the values for this product (RIS 203~RIS 208 A).

1. 1. Select the bore to suit the shaft or bearing

   The inner diameter d indicates the matching shaft or bearing bore, ranging from 5 to 45 mm in the listed products. For inner rings, check the shaft diameter and fit tolerance, and select a part number that matches the bearing dimensions. Mismatched dimensions can cause creep (slippage at the fitted surface) or assembly defects.

2. 2. Verify outer diameter and width against mating parts

   The outer diameter D ranges from 8 to 55 mm and the width B from 8 to 40 mm. For needle roller bearing inner rings, the outer diameter forms the roller raceway, so select it to match the inscribed circle diameter of the bearing, and select the width to suit the bearing width and the axial mounting space. Parts with the same bore often differ in width or type, so verify by part number.

3. 3. Select vibration-damping rings by bearing outer diameter

   This product: Compatible Bearing Outer Diameter 40 mm

   Rubber vibration-damping rings are fitted between the outer ring of a Y-bearing and the housing bore, so the applicable bearing outer diameter (40 mm for the listed product) must match the Y-bearing being used. Also confirm the applicable housing type, such as a sheet-steel pressed plummer block housing.

4. 4. Check the bolt diameter of fixing clips

   Fixing clips that prevent lock nuts from loosening are supplied with hex bolts and spring washers in some cases. Confirm that the applicable bolt size matches the nominal number of the HM lock nut to be combined, and determine in advance whether threaded holes must be machined.

5. 5. Confirm rubber material and operating temperature

   This product: Operating Temperature Range -30~+100 °C

   Vibration-damping rings made of NBR (nitrile rubber) are limited in operating temperature range due to the properties of the rubber. Consider the ambient temperature and heat generated by the bearing, and confirm that conditions fall within the operating temperature range. In environments exposed to oil or chemicals, also verify material compatibility.
