For rotating shafts in gearboxes, pumps, motors, and reducers, SKF CRWA1 R radial shaft seals retain lubricant and keep contaminants out. The CRWA1 R profile combines a sealing lip with a spring, which helps maintain contact while keeping friction low and resisting wear. These seals fit cylindrical housings and work with shafts machined to specific tolerances. MR Industrial Accessories supplies this line to customers across the United States and in several Latin American countries.

The part number follows a simple pattern: inner diameter x outer diameter x width, then the series code. Take 16X40X7 CRWA1 R: it fits a 16 mm shaft, a 40 mm housing, and is 7 mm wide. The CRWA1 R suffix defines the lip geometry and spring type. In this series, the digit after CRWA usually denotes a single-lip section, and the trailing R indicates a steel spring. Sizes in the range run from 16 mm to 90 mm inner diameter.

You will find these seals in speed reducers, centrifugal pumps, electric motors, compressors, machine tools, and gear transmissions. They also appear in food, chemical, and petrochemical operations, where preventing oil leaks and blocking dust or water matters. The radial design suits shafts turning at moderate to high speeds with low pressure on the fluid side.

Selection starts with three measurements: shaft diameter, housing diameter, and seat width. Check shaft roughness and hardness as well, because a worn or grooved shaft can damage the lip. During installation, lubricate the lip with the same oil or grease used in service, then press the seal in perpendicular to the shaft to avoid deformation. Shaft-to-housing alignment must be precise; too much misalignment speeds up wear. If the seal has a spring, keep it on the fluid side so it stays in place.

For equivalents, SKF CRWA1 R seals can be interchanged with other brands that use the same dimensional designation and lip type. You will often find matches in catalogs from manufacturers such as NAK, TTO, or Corteco, but confirm tolerances and lip material because they can differ. Interchangeability is not automatic: check that the lip profile, spring, and elastomer suit the fluid and operating temperature. When in doubt, ask our technical team.
