Oil seal (simering) 37x76x9.5/12, No name, model Czę001351

Radial oil seal (simering) with nominal dimensions 37×76×9.5/12 mm designed to prevent lubricant leakage and to keep contaminants out of rotating shafts and housings. This seal is intended for applications where a snug fit on a 37 mm shaft and a 76 mm bore is required. The profile with a 9.5/12 mm thickness and lip design provides a balance between sealing performance and mechanical fit in pumps, gearboxes, electric motors and general industrial machinery.

Advantages

The oil seal offers a compact radial seal profile suitable for standard rotating assemblies. Its dimensions ensure easy replacement where space and clearance match the 37×76×9.5/12 mm specification. The lip geometry is engineered to maintain lubricant retention while reducing the risk of external contamination ingress. Constructed for routine mechanical service, the seal provides consistent sealing behavior under normal operating conditions of rotating equipment.

Suitable for

• Pumps and pump shafts requiring radial sealing
• Gearboxes and transmission housings
• Electric motors and alternators with matching shaft/bore sizes
• Industrial machinery and rotating assemblies with these dimensions

Key specifications

• Inner diameter: 37 mm (nominal)
• Outer diameter: 76 mm (nominal)
• Cross-section / lip profile thickness: 9.5/12 mm
• Seal type: radial shaft seal (simering)
• Function: lubricant retention and contaminant exclusion

How to use

Select this oil seal when shaft and housing dimensions match the nominal 37×76×9.5/12 mm sizes. Before installation, inspect mating surfaces for burrs, corrosion, or wear and ensure the shaft and bore tolerances are appropriate for a press-fit radial seal. Lightly lubricate the sealing lip with the system lubricant to reduce initial friction during startup. Press the seal into the housing squarely using a suitable driver or tool, avoiding tilt or uneven force that can deform the lip. After installation, verify axial positioning and run the equipment briefly to confirm correct sealing and absence of leaks.

Usage recommendations

Store seals in a cool, dry place away from direct sunlight and ozone sources. For best performance, replace seals during scheduled maintenance when wear on shafts or housings is noted, and use compatible lubricants to avoid premature lip hardening or swelling.
