Rollway Bearings: Types, Series and Model Data
Identify the original Rollway bearing family, decode the complete part number and compare the dimensions and ratings in the supplied catalog. HSN can then review a stock or custom alternative against your operating conditions.
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.
Cylindrical Radial Roller
Standard and engineered radial designs with several locating and separable-ring configurations.
Cylindrical Roller Thrust
Inch-series single-acting, aligning and double-acting styles for axial loading.
Tapered Roller Thrust
TTHD and T-Flat designs use tapered rollers and different raceway arrangements.
Tandem Thrust
Several thrust stages share a constrained installation envelope; design and stage count must be checked.
Journal Roller
Steel-cage journal designs with separate catalog tables and specific mounting and fitting checks.
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.

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.
Have a Rollway Part Number?
Send the complete model, quantity, equipment position and operating conditions. Add a drawing, catalog page or old-bearing photos when available. HSN can review a stock or custom option and define the checks needed before confirmation.
