The DPH 140x170x17 IHHI/CASSETTE NBR is designed for a 140 mm shaft and a 170 mm nominal outer installation diameter, with an overall width of 17 mm.

Unlike a simple conventional radial oil seal, a cassette seal is an integrated sealing assembly. Depending on the specific design, the assembly may combine the dynamic sealing element, structural carrier, contamination-exclusion features, and a dedicated running surface or wear sleeve into one unit.

The exact IHHI construction is manufacturer-specific. Therefore, the following details should be verified before replacement:

• Number and sequence of sealing lips
• Dynamic and static sealing interfaces
• Integrated wear sleeve or running surface
• Dust and contamination-exclusion arrangement
• Internal metal carrier
• Spring or energizing configuration
• Lip orientation
• Rotating versus stationary elements
• Installation direction
• Axial installation position

This product uses NBR (Nitrile Butadiene Rubber), which is generally suitable for:

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

NBR generally offers good resistance to petroleum-based oils, grease, abrasion, and wear in industrial applications. Compatibility should be checked for aggressive chemicals, selected fuels, specialized synthetic lubricants, ozone-rich environments, and continuous elevated-temperature service.

Approximate inch dimensions are:

Shaft diameter: 140 mm / 5.512 in

Outer diameter: 170 mm / 6.693 in

Overall width: 17 mm / 0.669 in

The 140 × 170 × 17 mm size is a relatively large shaft-sealing assembly. Installation quality is particularly important. Shaft alignment, housing condition, concentricity, runout, installation depth, and correct cassette orientation should be controlled carefully.

📊 Specifications

Brand: DPH

Model / Profile: IHHI / CASSETTE

Size: 140 × 170 × 17 mm

Inch Equivalent: Approximately 5.512 × 6.693 × 0.669 in

Type: Integrated Cassette Rotary Shaft Seal

Material: NBR (Nitrile Butadiene Rubber) with manufacturer-specific internal support components

Profile: IHHI / CASSETTE

Construction: Manufacturer-Specific Integrated Cassette Seal Assembly

Lip Design: Cassette configuration; verify exact number, sequence, function, and orientation of sealing and exclusion lips against the original DPH seal or drawing

Dust Lip: May be integrated depending on the exact IHHI cassette construction; verify actual cross-section

Spring Type: Verify from the actual IHHI cassette construction

Wear Sleeve / Running Surface: Cassette seals may incorporate an integrated running surface or sleeve; verify the actual DPH IHHI design

Shaft Diameter (ID): 140 mm

Housing / Installation Diameter (OD): 170 mm nominal

Width: 17 mm

Pressure Capability: Primarily low-pressure rotary shaft service unless specifically rated otherwise by the manufacturer

Lubrication: Compatible oil and grease

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

Speed Consideration: Depends on shaft surface speed, cassette internal geometry, lubrication, temperature, runout, and actual IHHI design

Installation Consideration: Verify installation tool, insertion depth, cassette orientation, rotating/stationary interfaces, shaft and housing condition, concentricity, runout, and whether an integrated running sleeve is part of the assembly

Application Class: Heavy-Duty Industrial Bearing, Axle, Hub, Gearbox, and Transmission Equipment

Standard: Metric Manufacturer-Specific Cassette Seal Assembly

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• DPH IHHI Cassette Seal
• DPH 140x170x17 Oil Seal
• 140x170x17 Cassette Seal
• 140 mm Shaft Cassette Seal
• NBR Cassette Rotary Shaft Seal
• Heavy-Duty Bearing Cassette Seal
• Industrial Axle Cassette Seal
• Hub Cassette Seal
• Heavy Gearbox Cassette Seal
• OEM Integrated Rotary Seal Assembly

The same 140 × 170 × 17 mm dimensions alone do not guarantee interchangeability. A cassette seal must also match the original complete cross-section, number and sequence of sealing lips, rotating and stationary elements, integrated sleeve geometry, outside carrier construction, spring arrangement, sealing direction, axial position, installation direction, material, and operating requirements.

(Always verify complete IHHI cassette construction, shaft and housing dimensions, sleeve geometry, installation depth, orientation, shaft condition, housing condition, lubricant compatibility, rotational speed, temperature, concentricity, runout, pressure, and operating conditions before ordering.)
