Gearboxes and reducers
Shaft support where combined radial and thrust loads are present.
Industrial bearings
Tapered Roller Bearings
Type authority for tapered roller bearings: cup-and-cone geometry, combined radial and thrust capacity, applications and engineering selection guidance.
Overview
Tapered roller bearings use conical rollers between inner and outer rings (cup and cone) to support combined radial and axial loads. The tapered geometry directs load through the roller to the raceway at a controlled contact angle.
They are common in automotive wheel ends, gearboxes, heavy industrial drives and applications requiring stiff axial location alongside radial capacity. Single-row, paired and multi-row arrangements address different thrust and moment requirements.
Configurations and subtypes
Single-row tapered roller
One row of tapered rollers between cup and cone. Handles combined radial and thrust in one direction; a second opposed row or pair is used for reversing thrust.
Matched pairs and sets
Factory-matched sets control axial clearance and preload for precision spindle and gearbox arrangements.
Inch and metric series
Designation systems vary by manufacturer. Confirm bore, outside diameter, width and cone/cup pairing from catalogue data.
Applications
Wheel ends and transport
Hub and axle arrangements requiring high stiffness and load capacity.
Metal processing
Rolling mill and heavy-duty industrial drives with high combined loads.
Mining and construction
Equipment subject to shock loads and contamination.
Pumps and fans
Overhung load support on drive shafts.
Machine tool spindles
Precision paired arrangements where catalogue data supports the duty.
Engineering selection
Equivalent dynamic load
Radial and axial components
Combine radial and axial duty per manufacturer rating methodology before selecting designation.
Required life and reliability
L10 or application-specific life target
Match catalogue dynamic load rating to required service life at operating conditions.
Mounting and axial location
Cup/cone orientation and preload
Define fixed/float arrangement and whether paired mounting is required.
Speed and lubrication
Operating speed and temperature
Confirm speed factor, lubricant type and relubrication interval from catalogue.
Internal clearance and precision
Clearance class and tolerance grade
Variant attributes selected for fit, temperature rise and speed capability.

Engineering context
This page is a type authority reference for the Tapered Roller Bearings family within Golden Bearing Company’s industrial bearings taxonomy. It supports engineering selection and enquiry intent without a published designation catalogue.
Designation-level dimensions, load ratings and speed limits will be published on individual product pages only when backed by verified manufacturer source data. Until then, request quotation support with your part number, bore size and application duty.
Have a part number or designation?
Send manufacturer part numbers, bearing designations, bore sizes or operating context for engineering identification and quotation support.
This is an identification/interchange enquiry—not a live stock lookup or availability confirmation.
Common questions
The cone assembly includes the inner ring, rollers and cage. The cup is the outer ring. Both are required for a complete bearing; designations are often listed separately in catalogues.
When combined radial and axial loads are significant, or when stiff axial location is required. Ball bearings suit lighter combined loads and higher speed in many general-duty applications.
Provide manufacturer set or paired designation, bore, mounting arrangement and required clearance or preload. Engineering enquiry support is identification-based, not a live stock lookup.
