NBR65X90X10AS METRIC ROTARY SHAFT SEAL NITRILE AS (R23)

Oil Seals or Rotary Shaft Seals are designed to provide a barrier to retain lubricant and to keep out contamination. They are available in metric and imperial sizes with a variety of sealing lip arrangements. An Oil Seal (also known as a Shaft Seal, Lip Seal or Elastomeric Lip Seal), is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Generally, Oil Seals have been developed as a means of protecting the bearings of rotating shafts. R21 Oil Seals have a metal body which is rubber coated and contains a single sprung lip. R23 Oil Seals have an extra lip called a 'Wiper Lip', and are sometimes referred to as 'Double Lip'.
