For spindles and precision equipment that demand exact running accuracy and high rigidity, FAG super precision bearings in the M series provide consistent performance. MR Industrial Accessories LLC supplies these bearings to customers in the United States, Canada, Mexico, and South America. Our team can help you confirm the correct designation and suggest equivalents when needed.

The M series designation follows a structured format. The letter M marks the super precision range, and the four-digit number gives the bore size—M7005 is for a 25 mm shaft, M7006 for 30 mm, and M7007 for 35 mm. The suffix E stands for a 25° contact angle. The T and P4S combination defines the execution: T means a single-row bearing with a synthetic cage, while P4S is the super precision tolerance class. The XL suffix identifies the latest design generation.

Typical applications include spindles on milling, grinding, and machining centers where speed and precision are essential. You will also find these bearings in rotary tables, measuring heads, and high-resolution positioning systems. Maintenance and purchasing professionals in metalworking, automotive, and aerospace sectors rely on this series for tight-tolerance equipment.

When selecting a replacement, consider the complete designation rather than just bore and width. Contact angle, precision class, and cage type must match the original specification. Since different manufacturers use their own nomenclatures, interchangeability requires comparing technical characteristics, not just part numbers. If you are unsure, send us the full part number from the bearing or drawing.

Proper installation and lubrication are key to service life. These bearings are often mounted in pairs, back-to-back or face-to-face, depending on the spindle’s rigidity requirements. Use high-speed, clean oil or grease in the specified quantity to prevent overheating. Shaft alignment and housing fit must be precise; any deviation can reduce performance. Sealing, where applicable, helps keep contaminants out without adding excessive torque.
