The BGL KMTA is a precision lock nut designed to hold bearings firmly on machine tool spindles and other high-accuracy assemblies. Its locking mechanism uses three bolts positioned at 120 degrees that press pins against the shaft thread, creating a secure and repeatable hold. Unlike versions that need a hook wrench, this nut is tightened with a screw wrench. Made of carbon steel, it suits setups where vibration or changing loads might cause a standard nut to come loose.
The KMTA code works as a size guide: the letters indicate the series, and the number that follows gives the thread diameter in millimeters. For instance, KMTA5 fits an M25×1.5 thread (size code × 5), KMTA6 fits M30×1.5, and this pattern continues through KMTA12. This makes it straightforward to match the nut to your shaft. The KMTA series performs the same bearing-locking job as the KMT series, but the screw-wrench tightening method is an advantage when space is tight.
Typical applications include lathe, milling, and grinding machine spindles, as well as precision motors where axial play must be eliminated. You will also find them in machining shops, automated production lines, and machine tool maintenance. Because they resist loosening under vibration, they work well in continuously rotating equipment such as industrial fans or high-speed centrifugal pumps.
When selecting a lock nut, confirm the shaft thread diameter and pitch against the designation. Before mounting, clean the threads and apply the torque specified by the bearing manufacturer. Tighten the three locking bolts evenly to prevent distortion of the nut. Align the shaft and bearing before final securing, and check bolt tightness at regular intervals, since vibration can affect the locking force. Lubrication of the assembly also plays a role in service life.
Other brands offer precision lock nuts with similar locking systems, but dimensions and thread pitches can differ. If you are replacing a lock nut, compare diameter, pitch, and the type of wrench required. The BGL KMTA series is supplied by MR Industrial Accessories LLC. For a specific bearing, send us the exact part number and we will help you confirm the match.

Frequently asked questions
- How does a KMTA lock nut differ from a KMT?
- The KMTA is tightened with a screw wrench, while the KMT requires a hook or nut wrench. Both secure bearings on precision machines and use the same three-bolt locking system at 120 degrees.
- How do I choose the correct KMTA size?
- The number in the designation indicates the thread diameter in millimeters. For example, KMTA5 is for an M25×1.5 thread. Check the shaft diameter and pitch to ensure compatibility before requesting a quote.
- Where are KMTA lock nuts recommended?
- They are used on spindles of lathes, milling machines, precision motors, and rotating equipment where bearings must be securely fastened. They suit assemblies subject to vibrations or variable loads that could loosen a conventional nut.
