When you need a radial shaft seal for rotating equipment, the DBH 1229 offers a 38 mm shaft, 52.25 mm housing and 7.00 mm height. Its Lz design pairs a primary sealing lip with a secondary exclusion lip, so it handles dusty or dirty conditions while keeping lubricant in place. The seal presses into the housing and runs against the shaft on a lubricant film, which maintains sealing with minimal friction.

This radial shaft seal carries the DBH brand and part number 1229. The dimensions break down as 38 mm for the shaft (d), 52.25 mm for the housing bore (D) and 7.00 mm for the overall height (h). In the Lz configuration, the main lip does the sealing and a second lip sits outboard to block particles and hold grease. An elastomer that resists oils and greases forms the body, while a metal spring keeps steady pressure on the lip.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives — anywhere rotation requires lubricant retention. Agricultural and industrial settings with airborne dust benefit from the Lz exclusion lip as an extra barrier. Treat it as a wear part: replace it when leaks appear or bearings start making unusual noise.

Before installation, verify the shaft is 38 mm and has a suitable surface finish, free of burrs or marks that could cut the lip. The 52.25 mm housing must be clean and undistorted; a thin coat of lubricant compatible with the elastomer helps during pressing. The 7.00 mm height sets the axial space needed. For replacement selection, factor in rotation speed, operating temperature and the fluid being sealed. Choose the Lz design when dust or dirt exposure is expected.

To find an equivalent, send part number 1229 or the dimensions 38 x 52.25 x 7 mm through WhatsApp. You can also share shaft and housing measurements, lubricant type and service conditions. We review options within the same radial seal category and help you pick a part that seals correctly without modifying the equipment.
