801101745 CR HMS5 70×95×10 Radial Shaft Oil Seal for XCMG Loader Engine

801101745 CR HMS5 70×95×10 Radial Shaft Oil Seal — for XCMG Loader Engine & Rotating Machinery

The oil seal (Part No. 801101745, CR HMS5 type, 70×95×10) is a radial shaft seal​ designed for rotating shaft applications in XCMG loader engines and related drivetrain components . As a spring-loaded, single-lip rotary shaft seal, it retains lubricant (oil or grease) on the oil side while preventing contaminants from entering on the air side — a critical barrier protecting bearings, gears, and rotating assemblies from premature failure due to lubrication loss or particulate ingress.

Built to CR HMS5 / SKF HMS5 specification​ :

Performance envelope​ (per SKF official data) :

• Operating temperature:​ -40°C to +100°C (short-term up to 120°C)

• Max. circumferential speed:​ 9.2 m/s

• Max. rotational speed:​ 2520 r/min

• Pressure differential:​ 0.05 N/mm² (max 0.05 MPa / 7 psi)

• Lubricant compatibility:​ Mineral oils, grease, low-viscosity oils, synthetic lubricants (moderate temp.)

Key design advantages​ (from SKF CR HMS5 engineering notes) :

• The rubber outside diameter​ provides optimized sealing ability in the housing, even at considerable surface roughness or in split housings

• The beads on the outside diameter​ improve sealing ability and retention in the bore, and prevent spring-back during installation

• The spring-loaded sealing lip​ responds quickly to dynamic runout and maintains sealing performance even when lip wear is excessive

• The optimized NBR (RG) compound​ offers good resistance to ageing, very good pumping ability, and good wear resistance — rapidly returning oil from the air side to the oil side

Application & Compatibility
