The SKF CRSA P radial shaft seal is a lip seal used on rotating shafts to keep lubricant in and contaminants out. Pressed into the housing, its flexible lip runs against the shaft, tolerating minor misalignment while protecting bearings and bushings from dust, water and particles. For maintenance and purchasing teams, it is a small component that helps avoid leaks and unplanned downtime.
In a reference such as 125X146X14 CRSA1 P, the first three figures give the shaft diameter, housing bore and width in millimeters. CRSA denotes the construction family, while the final number and the P suffix identify lip and material options. When selecting a replacement, match all three dimensions and the full part number, because a different suffix can mean another elastomer or spring.
Typical installations include pumps, electric motors, gearboxes, conveyors, agricultural equipment and process lines. In food, chemical and petrochemical facilities, these seals help prevent leaks and cross-contamination. Maintenance workshops also use them when rebuilding gearboxes and rollers. The CRSA P series suits moderate peripheral speeds and medium sealing demands.
For selection, confirm shaft diameter, housing bore and available width. The lip must stay lubricated; dry running accelerates wear. Shaft-to-housing alignment matters, since excessive eccentricity leads to leakage. During installation, press on the outer edge with a suitable tool and avoid hitting the lip. If the shaft is worn, an auxiliary lip or a repair sleeve may be considered.
Radial shaft seals can be interchanged between manufacturers when dimensions and lip type agree. Diameter alone is not enough: width and lip profile must also be compatible. Brands such as SKF, NSK, Timken or NTN offer equivalents, but always verify the complete part number. MR Industrial Accessories supplies SKF and can help you identify the right reference if you send the dimensions or the number stamped on the old seal.
Before requesting a quote, inspect the shaft and housing. A new seal will not seal properly on a scratched or loose shaft. Send the complete part number via WhatsApp or email, along with dimensions if available, and the team will reply promptly with the correct reference and can suggest equivalents.

Frequently asked questions
- How do I identify the radial shaft seal I need?
- Measure the shaft diameter, housing bore and width. These three values define the size. Then determine lip type and material based on the fluid and temperature. If you have the old part number, send it complete; that is the most reliable way to get the right seal.
- Can SKF seals be interchanged with other brands?
- Yes, when dimensions and lip design match. Interchangeability depends not only on diameter: width, lip shape and material must be equivalent. Contact us with the original part number and we will indicate a compatible option.
- What should I watch for when installing a radial shaft seal?
- Lubricate the lip before installation, align shaft and housing, and use a tool that presses on the outer edge without striking the lip. Check that the shaft has no burrs or wear. Poor alignment or a damaged shaft can cause leaks even with a new seal.
