The FAG M7005-C-T-P4S-XL is a super precision bearing engineered for applications where running accuracy, rigidity, and high-speed capability are essential. It is commonly specified in machine tool spindles, grinding heads, and precision metrology equipment. MR Industrial Accessories LLC supplies this bearing to customers across the US, Canada, Mexico, and South America, with technical support to confirm the correct configuration.

The part number M7005-C-T-P4S-XL breaks down into distinct blocks. The leading M identifies the section series, while 7005 indicates the bore size. The suffix C specifies the contact angle, T denotes the synthetic-material cage, and P4S defines the precision class for high-speed operation. The XL marking corresponds to an improved design with reduced friction.

When selecting this bearing, consider the load type, operating speed, and required rigidity. Installation demands clean conditions, precise alignment, and correct lubrication—either grease or oil—depending on the duty cycle. Because P4S tolerances are extremely tight, mounting should be performed with proper tools and procedures to avoid premature wear.

Cross-brand equivalents exist, but they are not directly interchangeable without verifying dimensions, tolerances, and load ratings. Each manufacturer uses its own suffixes and classes, so any substitution requires technical evaluation. Contact MR to discuss compatibility and suitable options.
