The CR Oil Seal 2.000x2.565x0.500 HM14 NBR, Part No. 19757 is designed for industrial rotary shaft applications requiring dependable lubricant retention around a 2.000-inch shaft.

Installed between the rotating shaft and stationary housing, the sealing element creates controlled radial contact with the shaft surface. This helps reduce leakage of compatible oil or grease while protecting bearings, gears, pumps, transmissions, and other internal rotating components from dust, moisture, and contaminants.

This product is identified by:

• Brand: CR
• Part Number: 19757
• Profile: HM14
• Material: NBR

The HM14 designation is a manufacturer-specific profile code. The exact sealing-lip geometry, number of sealing elements, auxiliary exclusion feature, outside-case construction, internal reinforcement, spring arrangement, lip orientation, and installation direction should be verified against the original seal, technical drawing, or equipment specification before replacement.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element is generally suitable for:

• Mineral oils
• Gear oils
• Hydraulic oils
• Bearing grease
• Petroleum-based lubricants
• General industrial lubricating fluids

NBR provides good resistance to petroleum-based oils, grease, abrasion, and mechanical wear under standard industrial operating conditions. Compatibility should be verified before use with aggressive chemicals, fuels, high continuous temperatures, ozone-rich environments, or specialized synthetic lubricants.

The inch dimensions convert approximately to:

Shaft diameter: 2.000 inches or 50.80 mm

Housing diameter: 2.565 inches or 65.15 mm

Seal width: 0.500 inch or 12.70 mm

The 2.000 × 2.565 × 0.500-inch configuration is suitable for compact industrial bearing housings, gearboxes, pumps, transmissions, and legacy equipment using an inch-size shaft-sealing arrangement.

Model / Profile: HM14

Size: 2.000 × 2.565 × 0.500 inch

Metric Equivalent: Approximately 50.80 × 65.15 × 12.70 mm

Type: Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: HM14

Construction: Manufacturer-Specific HM14 Rotary Shaft-Seal Construction

Lip Design: HM14 profile; verify the exact sealing-lip geometry and orientation against the original seal or technical drawing

Dust Lip: Verify from the actual HM14 cross-section

Spring Type: Verify from the actual seal construction

Shaft Diameter (ID): 2.000 inches / 50.80 mm

Housing Diameter (OD): 2.565 inches / approximately 65.15 mm

Width: 0.500 inch / 12.70 mm

Pressure Capability: Low-pressure rotary shaft-sealing service unless otherwise specified

Lubrication: Compatible oil and grease

Temperature Range: Typically approximately -30°C to +100°C for standard NBR; verify the actual compound, lubricant, shaft speed, and operating conditions

Suitable replacement or cross-reference candidate for compatible:

• CR Part No. 19757 Oil Seal
• CR 2.000x2.565x0.500 Oil Seal
• CR HM14 NBR Shaft Seal
• 50.80x65.15x12.70 Rotary Seal
• 2.000-Inch Shaft Oil Seal
• Inch-Size NBR Rotary Shaft Seal
• Industrial Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Industrial Pump Shaft Seal
