The DICHTA Oil Seal 135x160x12 AS NBR is designed for industrial rotary shaft applications requiring lubricant retention around a 135 mm shaft within a 160 mm housing bore.

Installed between the rotating shaft and stationary housing, the sealing element maintains controlled radial contact with the shaft surface. This helps reduce leakage of compatible oil or grease while supporting protection of bearings, gears, pumps, motors, and other internal rotating components.

The product is identified by the DICHTA manufacturer designation AS. The exact sealing-lip geometry, number of lips, auxiliary contamination-exclusion arrangement, outside-case construction, internal reinforcement, spring configuration, lip orientation, and installation direction should be verified against the original seal, technical drawing, or DICHTA 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 normal industrial operating conditions. Compatibility should be verified before use with aggressive chemicals, fuels, specialized synthetic lubricants, ozone-rich environments, or continuous elevated-temperature service.

The dimensions are:

Shaft diameter: 135 mm

Housing diameter: 160 mm

Seal width: 12 mm

The 135 × 160 × 12 mm configuration is suitable for large bearing housings, gearboxes, pumps, transmissions, conveyor drives, and industrial machinery using a metric rotary shaft-sealing arrangement.

For a seal of this diameter, shaft finish, shaft hardness, housing alignment, concentricity, shaft runout, installation depth, and proper lubrication at the sealing interface are important factors affecting service life and sealing reliability.

📊 Specifications

Brand: DICHTA

Model / Profile: AS

Size: 135 × 160 × 12 mm

Type: Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: AS

Construction: Manufacturer-Specific DICHTA AS Rotary Shaft-Seal Construction

Lip Design: AS profile; verify exact sealing-lip geometry, number of lips, and orientation against the original seal or technical drawing

Dust Lip: Verify from the actual AS cross-section

Spring Type: Verify from the actual seal construction

Shaft Diameter (ID): 135 mm

Housing Diameter (OD): 160 mm

Width: 12 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

Speed Consideration: Permissible speed depends on shaft diameter, surface finish, lubrication, temperature, alignment, concentricity, runout, lip loading, and NBR compound

Installation Consideration: Confirm shaft finish, shaft hardness, housing-bore condition, installation depth, lip direction, concentricity, and protection from sharp shaft edges before fitting

Application Class: Large Industrial Bearing and Rotating Equipment

Standard: Metric Industrial Rotary Shaft Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• DICHTA AS NBR Rotary Shaft Seal
• DICHTA 135x160x12 Oil Seal
• 135 mm Shaft Oil Seal
• 135x160x12 NBR Oil Seal
• Metric NBR Rotary Shaft Seal
• Industrial Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Industrial Pump Shaft Seal
• OEM AS Profile Oil Seal
• Large Industrial NBR Shaft Seal

The same dimensions alone do not guarantee interchangeability. The replacement must match the original AS cross-section, sealing-lip geometry, lip orientation, outside-case construction, reinforcement arrangement, spring configuration, installation direction, material compound, and operating requirements.

(Always verify dimensions, AS-profile geometry, lip direction, shaft finish, shaft hardness, housing condition, installation depth, lubricant compatibility, rotational speed, temperature, alignment, concentricity, runout, pressure, and operating conditions before ordering.)
