SKF Nitrile Rubber (NBR) Seal, 35 mm ID, 52 mm OD, 7 mm

This seal is a rotary shaft sealing component designed to separate rotating and stationary machine parts and retain lubricants in dynamic joints. It features an elastomeric sealing lip with a garter spring and a rubber outside diameter, intended for use with oil or grease in industrial rotating assemblies where controlled leakage and contamination exclusion are required.

• Permissible circumferential speed 6.4m/s improves operational throughput
• Operating temperature range −40°C to 100°C extends service life
• Short-term temperature tolerance up to 120°C permits thermal excursions
• Pressure differential 0.03N/mm helps maintain lubricant retention
• Garter spring maintains consistent radial load for sealing reliability
• Accommodates misalignment to reduce shaft wear and downtime

• Suitable for automation drive shafts requiring oil retention
• Ideal for electrical motor shafts in industrial equipment
• Used with gearboxes that handle grease or oil lubrication
• Can be used for rotating assemblies in electronics manufacturing
• Used for maintenance replacement in mechanical drive systems

The sealing lip is MADE from nitrile rubber (NBR) and the outside diameter is rubber with metal reinforcement to provide a flexible press-fit in the housing.

It is rated for up to 3 480r/min under the specified circumferential speed limit.

The conventional lip geometry combined with the garter spring permits slight radial and angular deviations while maintaining contact and sealing performance.

A Speedi-Sleeve can be used to repair scored shafts before fitting the seal to restore correct running surfaces.
