Ball Bearing 134-746 BD TNG 2RS MGK (39x68x37 mm)

Technical Specifications & Key Features

The 39 x 68 x 37 mm double-row bearing with designation 134-746 BD TNG 2RS MGK is engineered for demanding industrial applications where high durability and dependable performance are required. This angular contact ball bearing supports both radial and axial loads thanks to its specially designed raceways and contact angle configuration. The “2RS” two-side rubber seal effectively keeps contaminants out and retains lubricant, thus prolonging service life and reducing maintenance needs. The designation “TNG” refers to the cage material or design family suited for robust applications. Dimensions: inner diameter (d) = 39 mm, outer diameter (D) = 68 mm, width (B) = 37 mm.

Designed as a bearing unit inside a bearing housing or as part of a bearing assembly (bearing housing configuration), this unit is suitable for integration into applications requiring compact size and high performance. The double-row angular contact construction ensures stability under combined loading conditions typical in industrial drives, gearboxes, and rotating assemblies.

Key features:

• Nominal dimensions 39x68x37 mm - facilitating direct replacement in standard machine units.

• Angular contact double-row design - allows simultaneous radial and axial load handling for extended lifetime.

• 2RS sealing - prevents ingress of dust, moisture and ensures consistent lubrication.

• Engineered for industrial bearing housings and units - optimal for B2B procurement.

Industrial Applications & Benefits

This angular contact ball bearing 134-746 BD TNG 2RS MGK is ideal for usage in industrial environments such as gearboxes, shaft drives, machine tools, bearing housings, and units where high reliability and longevity are critical. In particular, when installed inside a bearing housing or unit, it meets requirements for high-duty rotation, minimal downtime and cost-efficient maintenance.

Benefits:

• Reliable integration into bearing housings and units thanks to precise sizing and robust design.

• Significantly reduced maintenance thanks to sealing and high-quality internal construction.

• Uninterrupted operation in production equipment and industrial drives - supporting heavy loads and combined stresses.

• Excellent purchase option for procurement teams sourcing angular contact ball bearings in B2B channels.

FAQ

Q1: Can this bearing handle axial loads in both directions?
Yes - the double-row angular contact design allows it to support axial loads in both directions, in addition to radial loads, making it well-suited for demanding industrial drives.

Q2: What does “2RS” mean and how does it benefit longevity?
“2RS” indicates rubber seals on both sides of the bearing, which block dust and moisture ingress and maintain lubrication, thus extending service life and reducing downtime.

Q3: Is the 39x68x37 mm dimension a standard size for angular contact ball bearings?
Yes - this dimension appears in industry catalogs and is commonly used in machine units and bearing housings needing combined load support and compact installation.

Q4: What is the significance of “TNG” in the designation?
“TNG” refers to the type of cage or internal design family optimized for angular contact ball bearings operating under demanding conditions. It ensures structural integrity and stable performance.
