The SKF KMTA series is a line of precision lock nuts used to hold bearings in place on a shaft. They suit assemblies where the fit has to stay exact and the fastening has to hold. Mounting and removal are straightforward, which helps when rotating equipment has to be serviced. MR Industrial Accessories LLC supplies this series within its range of power transmission and bearing mounting products.
Reading the code is the quickest way to pick the right nut. KMTA identifies the series, and the digits after it give the shaft diameter in millimeters. KMTA 5, for instance, is built for an M25×1.5 thread, while KMTA 7 takes an M35×1.5 thread. Confirm the full part number when you send your inquiry so the thread matches your shaft.
These nuts turn up in food processing, metallurgy, petrochemical and mining operations, and in pumps, fans, conveyor belts, machine tools and continuous process lines. Their job is to stop the bearing from shifting along the shaft, which keeps the assembly accurate. They are a practical choice where there is little room to work and the fixing has to be dependable.
Selection starts with two details: the shaft diameter and the bearing being secured. Check the thread and pitch, and note how the nut locks, whether through set screws or a safety plate. Before mounting, clean the threads and tighten to the torque the manufacturer specifies so nothing works loose. A light application of lubricant on the thread eases adjustment and limits wear.
Lock nuts that follow the same dimensional standard can be swapped between makers, so the SKF KMTA series has equivalents elsewhere. Tolerances and material still need checking to confirm the substitute performs the same way. MR Industrial Accessories LLC can point you to alternatives from other recognized brands, and our technical team will review your application with you.

Frequently asked questions
- How do I read an SKF KMTA part number?
- KMTA is the series, and the number after it is the shaft diameter in millimeters. KMTA 5 fits an M25×1.5 thread; KMTA 7 fits an M35×1.5 thread. Matching that number to your shaft size is the first step in selection.
- What do I need to check before mounting a KMTA lock nut?
- Confirm the shaft diameter and the bearing being secured, then verify the thread and pitch and the locking method, either set screws or a safety plate. Clean and lubricate the thread, then tighten to the manufacturer's recommended torque.
- Can another brand's lock nut replace an SKF KMTA nut?
- Often yes, provided it follows the same dimensional standard. Check tolerances and material to confirm equivalent performance. Our team can review compatible options for your application when you send your part number.
