SKF Nitrile Rubber (NBR) Seal, 38 mm ID, 58 mm OD, 8 mm

This seal is a rotary shaft sealing solution designed to separate rotating and stationary components, preventing lubricant loss and excluding contamination in machinery. It employs an elastomeric contact lip and a supplementary non-contact lip to maintain fluid retention in applications where oil or grease is present, while coping with shaft movement and environmental particulates.

• Garter spring maintains consistent radial force for sealing integrity
• Auxiliary non-contact lip improves exclusion of dust and debris
• Accommodates shaft misalignment to reduce leakage risk
• Permits circumferential speeds up to 6.72 m/s for rotating systems
• Withstands continuous temperatures from -40°C to 100°C

• Suitable for gearboxes requiring oil containment under moderate speeds
• Ideal for motor shafts in automation equipment
• Used with bearings in industrial electric drives
• Can be used for sealing rotating shafts in process machinery

The primary sealing lip is MADE from nitrile rubber (NBR), chosen for compatibility with oils and common greases.

A combination of elastomeric flexibility and the garter spring permits radial compliance to tolerate misalignment without losing contact.

Short-duration exposure up to 120°C is acceptable, beyond the continuous operating upper limit.

The seal is rated for rotational speeds up to approximately 3360 r/min under its maximum permissible circumferential speed.
