Which Rollway Bearing Type Do You Have?

The supplied catalog concentrates on cylindrical roller designs for radial and axial loads. It also covers tapered thrust, tandem thrust and steel-cage journal roller bearings.

01 / RADIAL

Cylindrical Radial Roller

Standard and engineered radial designs with several locating and separable-ring configurations.

MAX NU · NJ · NUP · N
02 / AXIAL

Cylindrical Roller Thrust

Inch-series single-acting, aligning and double-acting styles for axial loading.

T · AT DT · DAT · SDT
03 / AXIAL

Tapered Roller Thrust

TTHD and T-Flat designs use tapered rollers and different raceway arrangements.

T-### T-#####-F
04 / MULTI-STAGE

Tandem Thrust

Several thrust stages share a constrained installation envelope; design and stage count must be checked.

TAB…TAH TMB…TMH
05 / JOURNAL

Journal Roller

Steel-cage journal designs with separate catalog tables and specific mounting and fitting checks.

02 · DESIGNATION GUIDE

Series and Part Number Structure

The prefix can indicate a different ring arrangement even when the nominal dimensions look similar. Retain every suffix and variation code when sending an inquiry.

Radial: MAX numbering

MCS-5222-103 = prefix + size designator + variation

The catalog lists ML, MCS, MN, MS, M, MUC, MUL, MU and MR configuration prefixes. It identifies 100, 200, 300, 5000 and 5100 size-designator series for this numbering section. Special variation codes require the original engineering definition.

Radial: ISO numbering

NU-320-EMC3 = prefix + size designator + variation

NU, NUP, NJ and N describe different separable and locating arrangements. Series in this section include 200, 300, 2200 and 2300. E, M and C3 have catalog-defined meanings; special VAA-style codes need further confirmation.

Cylindrical thrust families

T-###  ·  AT-###  ·  CT-##  ·  DT-###  ·  DAT-###  ·  SDT-###

T denotes cataloged thrust styles; AT adds aligning plates in the illustrated series. Double-acting variants have their own construction. Verify the exact assembly and load direction.

Tapered, tandem and journal

T-###  ·  T-#####-F  ·  TAB…TAH  ·  TMB…TMH  ·  B/D/WS/E

These identifiers refer to separate product families and data tables. The shared letter T does not make tapered and cylindrical thrust designs interchangeable.

What a suffix can change

Depending on the designation, a suffix may specify internal clearance, retainer design, extra capacity, temperature stabilization or a special engineering variation. A base number is insufficient to confirm the replacement.

04 · TECHNICAL ASSESSMENT

What HSN Checks Before Proposing an Alternative

The Rollway catalog provides an identification starting point. A replacement also depends on installation details and agreed inspection requirements.

Complete designation

Prefix, base size, suffixes and special variation codes.

Geometry and assembly

Bore, OD, width/height, shoulders, fillets, separable rings and plate arrangement.

Loads and operating speed

Radial or axial direction, duty cycle, lubrication and temperature.

Materials and internal design

Cage, clearance, precision, seals and any high-temperature or special material requirement.

Fits and surrounding equipment

Shaft, housing, bearing position and room for aligning or tandem assemblies.

Acceptance before shipment

Drawing, applicable standards, inspection items and customer-agreed criteria.

REQUEST AN ASSESSMENT
