NUTR50110-X Support Roller Bearing

The NUTR50110-X is a yoke-type support roller bearing with a 50 mm bore, 110 mm outside diameter, and 32 mm overall width. It is designed for track-guided, cam-follower, and rolling-contact applications in industrial machinery, conveying equipment, and material-handling systems.

Its double-row full-complement cylindrical roller arrangement provides high radial load capacity within a compact design. The rated dynamic load (Cr) is 76 kN and the static load (Cor) is 128 kN per the supplier drawing. The inner ring has two fixed flanges, allowing the roller set to be guided axially.

The bearing uses CN radial clearance (0.030–0.060 mm) and is sealed on both sides per the supplied configuration. Actual load capacity and operating suitability depend on the bearing specification and working conditions.

EKB supplies NUTR50110-X support rollers for industrial replacement and equipment maintenance. Contact us to confirm the required specification, availability, and lead time.

Product Specifications

Note: Confirm the complete dimensions and technical specifications against the supplier's drawing before ordering or replacing an existing bearing.

Key Features

• Double-Row Full-Complement Cylindrical Rollers
  The full-complement arrangement maximizes the number of rolling elements, supporting high radial load capacity (Cr 76 kN / Cor 128 kN) within a compact 50×110×32 mm envelope.

• Fixed Inner-Ring Flanges
  The inner ring has two fixed flanges that axially guide the roller set, suitable for yoke-type and track-guided mounting arrangements.

• CN Radial Clearance
  CN clearance (0.030–0.060 mm) is suitable for general industrial operating conditions. Confirm clearance requirements for special temperature or precision applications.

• Sealed Both Sides
  The bearing is sealed on both sides to retain lubricant and limit the entry of contaminants. Seal configuration should be confirmed for the intended operating environment.

• Specification-Based Replacement
  When replacing an existing NUTR50110-X, check the complete dimensions, flange configuration, sealing, and clearance rather than matching the model number alone.

Measured Dimensions & Quality Verification

Every NUTR50110-X supplied by EKB is 100% dimensionally inspected before shipment.

The measured dimensions of each bearing are verified to be within the tolerance ranges specified by the national standard (GB/T). Actual measurement data and the dimensional drawing are available on request.

Typical Applications

NUTR-type support rollers are commonly used in:

• Track-guided conveying systems

• Cam and track mechanisms

• Material-handling and lifting equipment

• Guide-roller assemblies in industrial machinery

• Metalworking and textile machinery

• Other yoke-type track roller applications

Please provide the equipment model or application details when requesting a replacement. This helps determine whether the bearing is suitable for the actual working conditions.

Dimensions and Replacement Compatibility

The basic dimensions of NUTR50110-X are:

• Bore: 50 mm (1.969")

• Outside diameter: 110 mm (4.331")

• Inner ring width: 32 mm (1.260")

• Outer ring width: 30 mm (1.181")

• Inner ring shoulder diameter (d2): 59.8 mm (2.354")

Other important details include the roller arrangement, flange configuration, sealing, clearance, and load rating.

A bearing with the same bore, outside diameter, and width is not necessarily an interchangeable replacement. In particular, NUTR50110-X and PWTR50110-2RS share similar envelope dimensions but differ in roller type, sealing, and internal construction — they should not be treated as interchangeable without checking the equipment.

If you are replacing an existing bearing, please send the original part number, dimensional drawing, photographs, or a physical sample. EKB can help check the available specification before an order is placed.
