Timken LM67048-90015 Back to Back Spacer Tapered Roller Bearing Assembly

Description:

The Timken LM67048-90015 is a factory-matched back-to-back spacer tapered roller bearing assembly consisting of two single-row tapered roller bearings mounted in a back-to-back (indirect mount) configuration with precision inner and outer spacers that establish the preset bench end play or preload. Unlike individual cones or cups, this is a complete matched bearing assembly with components that are factory matched and are not intended to be mixed with components from other assemblies. Commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems, this assembly provides high rigidity, accurate shaft positioning, simplified installation, and dependable long-term performance. Maintenance teams, OEMs, and system integrators specify the Timken LM67048-90015 back-to-back spacer tapered bearing assembly for equipment repair, replacement, machine rebuilds, and retrofits where factory-preset bearing adjustment reduces installation time and improves reliability.

Applications:

The Timken LM67048-90015 back-to-back spacer tapered roller bearing assembly is engineered for heavy-duty industrial applications requiring reliable support for combined radial and axial loads with controlled internal clearance. It is widely used in industrial gear reducers, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems where the factory-matched spacer assembly delivers precise shaft alignment, efficient load distribution, increased rigidity, and extended bearing service life while eliminating manual bearing clearance adjustment during installation.
