Matched Tapered Roller Bearings
Matched tapered roller bearings are designed to offer enhanced rigidity and precision in high-load applications. They are commonly arranged in face-to-face, back-to-back, or tandem configurations, providing excellent thrust capacity and load distribution. These bearings effectively handle both radial and axial loads and are ideal for applications requiring high accuracy and durability.
- High load capacity
Matched bearings handle heavy radial and axial loads, with axial capacity increasing as the contact angle α grows (10°-30°). - Axial loads in both directions
Matched bearings can support axial loads in both directions with specific clearance or preload. - High stiffness
Matched bearings provide a stiff arrangement based on design. - Ready-to-mount sets
Bearings and ring spacers are matched in production and delivered as a set. - Low friction
Optimized raceway design promotes true rolling action, reducing friction, noise, and wear. - Long service life
Crowned and logarithmic raceway profiles enhance load distribution and reduce stress and misalignment. - Reliability
Optimized surface finishes improve lubricant film formation, enhancing operational reliability. - Consistency
Close tolerances in roller manufacturing ensure even load distribution, reducing noise and vibration. - Reduced running-in temperature peaks
AMIGO bearings reduce friction and heat during the running-in period, minimizing wear.

Matched Tapered Roller Bearings - Designs and Variants
Matched Bearings Arranged Face-to-Face
Matched bearings in a face-to-face arrangement offer flexibility and accommodate misalignment. This setup is ideal when axial loads in both directions are expected and radial stability is crucial.
Matched Bearings Arranged Back-to-Back
Back-to-back arrangement provides high rigidity and is best suited for applications where high radial and axial loads need to be absorbed from opposite directions. It enhances load-carrying capacity.
Matched Bearings Arranged in Tandem
A tandem arrangement focuses on handling significant axial loads in one direction. This setup helps distribute the load evenly across the bearings, increasing operational stability.
AMIGO Explorer Bearings
AMIGO Explorer bearings are engineered for exceptional performance with improved internal geometry and surface finish, offering higher load-carrying capacity, longer service life, and reduced friction.
