A cylindrical roller bearing is a precision internal gearbox component designed to support rotating transmission shafts while allowing them to operate with minimal friction. Unlike a conventional ball bearing, it uses cylindrical rollers to provide a relatively large contact area between the rolling elements and bearing races, making this bearing type particularly well suited to carrying significant radial loads.
Inside a gearbox, accurate shaft support is critical. Gears must remain correctly positioned relative to one another so their teeth mesh as intended. Excessive bearing wear can allow unwanted shaft movement, potentially resulting in noise, vibration, poor gear engagement and accelerated wear of other transmission components.
This OE Match Gearbox Cylindrical Roller Bearing provides a high-quality replacement for a worn or damaged original bearing during gearbox repair, overhaul or restoration.
What This Product Does:
- Supports a rotating shaft within the gearbox.
- Carries radial loads generated during transmission operation.
- Allows the supported shaft to rotate with low friction.
- Helps maintain accurate shaft alignment.
- Helps maintain correct gear positioning and mesh.
- Reduces unwanted movement within the transmission.
- Supports smooth gearbox operation.
- Helps distribute loads through the bearing surfaces.
- Contributes to reliable transmission operation under varying loads.
- Helps prevent excessive shaft movement.
- Replaces a worn, noisy or damaged gearbox bearing.
- Provides an OE Match replacement for compatible Porsche transmissions.
Symptoms Of Wear Or Failure:
- Whining from the gearbox.
- Rumbling or growling noises.
- Grinding noises from the transmission.
- Noise that changes with road speed.
- Noise that changes depending on the selected gear.
- Increased gearbox vibration. Excessive transmission shaft play.
- Difficult or inconsistent gear selection. Gear lever vibration.
- Transmission noise under acceleration.
- Noise becoming more noticeable on overrun.
- Metallic particles found in the gearbox oil.
- Visible wear or pitting on the bearing surfaces.
- Damaged cylindrical rollers.
- Discolouration caused by excessive heat.
- Roughness when rotating the bearing by hand during overhaul.
- Excessive internal bearing clearance.
- Damage discovered during gearbox disassembly.
Why Replacement Matters:
- Transmission bearings maintain the precise relationship between shafts, gears and other rotating components.
- As a bearing wears, its internal clearances can increase. This can allow the supported shaft to move beyond its intended position. Even relatively small amounts of unwanted movement can affect how transmission gears engage and transfer load.
- A deteriorating bearing may initially produce only a faint whine or rumble. As wear progresses, vibration and shaft movement can increase and place additional loads on neighbouring gearbox components.
- Replacing a worn OE Match Cylindrical Roller Bearing during the early stages of deterioration can help prevent a relatively contained bearing repair from developing into a more extensive gearbox rebuild.

OEMatch Bearings / Bearing Retaining Plates / Bushes — Fit, Function, Confidence
OEMatch supplies bearings, retaining plates and bushes for Porsche models, intended to support gearbox rebuilds, maintenance and restoration projects. These precision parts maintain shaft alignment, reduce friction and control vibration to preserve gearbox behaviour across road and competition applications. OEMatch catalogs over 4,000 individual part numbers and more than 8,700 OE cross-references, and continues to develop new lines for Porsche applications.
Available Types
- Individual gearbox bearings for input, layshaft and output shafts
- Machined and pressed bearing retaining plates and covers
- Polymer and metal bushings supplied as single items or repair kits
Understanding OEMatch Bearings / Bearing Retaining Plates / Bushes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original bearings, retaining plates and bushes.
OE (Original Equipment) refers to parts matching original specifications for the bearings, retaining plates and bushes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM bearings, retaining plates and bushes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Bearings, retaining plates and bushes support rotating assemblies and keep gearsets correctly aligned. Bearings reduce friction between moving parts, retaining plates fix bearing position and resist axial movement, and bushes absorb side loads and damp vibration. Correct material, heat treatment and machining tolerances are key for reliable service life in Porsche gearboxes.
Benefits Include
- Restored gear alignment and smoother gear engagement
- Reduced friction and lower operating temperatures
- Less vibration and quieter gearbox operation
Why Bearings / Bearing Retaining Plates / Bushes Wear and Fail
- Insufficient or contaminated lubrication leading to accelerated bearing wear
- Heat damage and material fatigue from sustained high loads
- Corrosion and contamination from moisture or debris ingress
The Importance of Replacing with OEMatch Bearings / Bearing Retaining Plates / Bushes
Replacing worn bearings, retaining plates and bushes restores precise shaft support and prevents secondary damage to gears and shafts. Using well-specified replacements reduces the risk of noise, shifting issues and rapid re-wear after a rebuild. For Porsche gearboxes, matching materials and tolerances helps maintain intended clearances and load distribution, which is especially important where high revs and sustained torque are encountered.
Advantages
- Parts selected for Porsche applications and cross-referenced to common original numbers
- Options for standard replacement or upgraded materials where listed
- Kits and individual items to suit full rebuilds or targeted repairs
