The KACO Oil Seal 45x62x10/12 DGS NBR is designed for rotary shaft applications requiring lubricant retention around a 45 mm shaft within a 62 mm housing bore.

The size designation 10/12 mm indicates a stepped or differential axial profile in which the main body and overall lip/profile envelope may have different axial dimensions. The exact shoulder, secondary-lip projection, flange geometry, and installation depth should therefore be checked against the original seal or technical drawing.

The KACO DGS profile is commonly configured with a primary sealing lip and an auxiliary secondary lip. A garter spring is typically used to maintain radial loading at the primary sealing lip, while the second lip assists with contamination exclusion or secondary sealing depending on installation orientation.

Because DGS is a manufacturer-specific KACO profile, the precise cross-section, lip orientation, case reinforcement, spring arrangement, and meaning of the 10/12 mm stepped width should be verified before interchange.

Manufactured from NBR, the seal is generally suitable for:

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

NBR provides good resistance to oils, grease, abrasion, and mechanical wear under normal industrial conditions. Compatibility should be verified before use with aggressive chemicals, certain fuels, ozone-rich environments, specialized synthetic fluids, or continuous elevated temperatures.

The dimensions are:

Shaft diameter: 45 mm

Housing diameter: 62 mm

Nominal width: 10/12 mm stepped or differential-width configuration

The 45 × 62 × 10/12 mm size is suitable for compact-to-medium bearing housings, gearboxes, electric motors, pumps, transmissions, and OEM machinery requiring a KACO DGS-style sealing arrangement.

📊 Specifications

Brand: KACO

Model / Profile: DGS

Size: 45 × 62 × 10/12 mm

Type: Double-Lip Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: DGS

Construction: Manufacturer-Specific KACO DGS Rotary Shaft-Seal Construction

Lip Design: Commonly a primary sealing lip plus an auxiliary secondary lip; verify exact geometry and direction

Dust Lip: Commonly incorporates an auxiliary lip for contamination exclusion; verify actual DGS configuration

Spring Type: Commonly a garter spring on the primary sealing lip

Shaft Diameter (ID): 45 mm

Housing Diameter (OD): 62 mm

Width: 10/12 mm stepped or differential-width profile

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 KACO compound, lubricant, shaft speed, and operating conditions

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

Installation Consideration: Confirm the 10/12 mm stepped geometry, installation depth, lip direction, shaft finish, housing-bore condition, and axial clearance before fitting

Application Class: General Industrial Bearing and Rotating Equipment

Standard: Metric Specialized Rotary Shaft Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• KACO DGS NBR Rotary Shaft Seal
• KACO 45x62x10/12 Oil Seal
• 45x62x10/12 Double-Lip Oil Seal
• 45 mm Shaft NBR Seal
• Double-Lip Rotary Shaft Seal
• Spring-Loaded Oil Seal
• Industrial Bearing Housing Seal
• Electric Motor Shaft Seal
• Industrial Gearbox Oil Seal
• OEM DGS Profile Seal

The same nominal dimensions alone do not guarantee interchangeability. The replacement must match the original DGS cross-section, 10/12 mm stepped geometry, primary-lip profile, auxiliary-lip geometry, spring arrangement, lip orientation, outside construction, material compound, and installation depth.

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