CR Seals (SKF) 9934 Single Lip Oil Seal, 1 Inch Shaft Diameter, CRW1 Design, Nitrile rubber (NBR) Material

Chicago Rawhide Part Number: 9934

SKF Part Number: 9934

Design Series: CRW1

9934, SKF, Radial shaft seal with metal case and SKF Wave lip CRW Black 3D

Rotating and stationary machine parts, as well as parts moving relative to one another, are sealed by radial shafts. The design of CRW1 seals includes a metal casing, an elastomer SKF Wave lip with a higher pumping rate to minimize heat generation, and a garter spring to maximize sealing against the shaft. Small flaws in the housing bore are filled up by the SKF Bore Tite coating on the outside diameter of the majority of seals.

PRODUCT HIGHLIGHTS

• For grease or oil
• The Wave lip increases the pumping pace when using a garter spring
• Less friction between the shaft and the lip with a Wave lip
• The temperature of the Wave lip is lower near the contact point
• The SKF Wave lip seal offers the greatest pump rate in the industry and features a metal OD
• This seal's sinusoidal motion reduces heat production by up to 30% and friction by 20%
• Secure and precise fit in the housing bore and ease of installation

CRW1, CRWA1, CRWH1 and CRWHA1 seals

As part of the CR Seals collection, the radial shaft seals CRW1, CRWH1, CRWA1, and CRWHA1—also known as SKF Wave seals—are low-friction seals with an SKF Wave lip design for less heat generation. Refer to the Sealing lip design section for more details. They fit precisely and firmly in the housing bore because to their metal exterior diameter, which also makes installation simple. The CRWA1 and CRWHA1 seals, in particular, which include an auxiliary lip, are ideal for contamination exclusion even though their primary purpose is to retain lubricants. The sealing lips for all of these seals are composed of either nitrile rubber or SKF Duralife, a fluoro rubber combination that was created by SKF.

Key characteristics include

• CRW1: Seal with a single steel case, SKF Wave lip and a carbon steel garter spring
• CRWH1: Seal with a double steel case, SKF Wave lip and a carbon steel garter spring
• CRWA1: Seal with a single steel case, SKF Wave lip , a carbon steel garter spring and an auxiliary, non-contacting lip
• CRWHA1: Seal with a double steel case, SKF Wave lip , a carbon steel garter spring and an auxiliary, non-contacting lip

APPLICATIONS

• Gearboxes
• Hydraulic pumps
• Axles
• Power steering columns
• Speed reducers
• Transmissions

Radial shaft seals are positioned between two components that are moving relative to one another or between fixed and rotating components. They are divided into two major sections. One is a cylindrical outer covering that fits into the housing bore statically and has an interference fit. The second is a sealing lip that seals against the shaft both statically and dynamically. With a predetermined radial load, its sealing edge presses up against the shaft's counterface surface. There are numerous uses for Maxtran's radial shaft seals. Both SKF and users are significantly interested in standardizing due to the significance of radial shaft seals for machine operational dependability and service life. For the widest selection of oil seal sizes and materials, you can rely on Maxtran.

This 9934, SKF, Radial shaft seal with metal case and SKF Wave lip CRW Black 3D oil seal sold by Maxtran is manufactured by Chicago Rawhide, an SKF company from high quality materials. This SKF Radial shaft seal has a Nitrile rubber (NBR) Single lip and is designed with a CRW1 lip profile. This 9934 oil seal can be used where fitament requires a 1 Inch shaft and 1.624 Inch outside diameter rotary seal needing a 0.25 Inch overall seal thickness.
