The DICHTA 28x37x4 DINAW NBR Oil Seal is engineered for rotating equipment requiring dependable sealing performance in compact installation spaces. It is widely used in electric motors, industrial pumps, precision gearboxes, hydraulic equipment, machine tools, automation systems, compressors, and OEM machinery where reliable lubricant retention is essential.

The DINAW Profile is a compact rotary shaft oil seal specifically designed for applications with shallow housing depths while maintaining excellent sealing performance. Its construction incorporates a reinforced metal case combined with a spring-loaded primary sealing lip, providing dimensional stability, secure housing retention, and consistent sealing force throughout the service life of the seal.

The integrated garter spring continuously maintains radial sealing pressure against the rotating shaft, effectively minimizing lubricant leakage while protecting bearings, shafts, and internal rotating components from premature wear.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this oil seal provides excellent resistance to:

• Mineral oils
• Hydraulic oils
• Gear oils
• Lubricating grease
• Petroleum-based lubricants

NBR offers excellent abrasion resistance, elasticity, and long-term durability for general industrial applications. Typical operating capability is up to 0.5 Bar, with operating temperatures ranging from -40°C to +100°C, depending on shaft speed, lubrication, and operating conditions.

With dimensions of 28 × 37 × 4 mm, this compact oil seal is commonly installed in electric motors, industrial pumps, precision gearboxes, hydraulic equipment, machine tools, conveyor systems, automation equipment, and OEM machinery requiring metric shaft sealing solutions.
