1 Pair H7201C (7201) Sealed Angular Contact Spindle Bearings — 12 x 32 x 10 mm, 2RZ, P4, DBA Designed for precision spindles and speed rotary applications, this matched pair of H7201C angular contact bearings delivers stable axial support, low runout, and protection against contamination. Key benefits Precision performance: P4 accuracy grade reduces vibration and runout for smoother, more accurate spindle rotation. Ready for assembly: Supplied as a matched pair in DBA (backtoback) arrangement for reliable axial load support in both directions and predictable preload behavior. Protection and maintenance savings: 2RZ double rubber seals (sealed both sides) help keep lubricant in and contaminants out, extending bearing life and reducing maintenance frequency. Compact fit for small spindles: 12 x 32 x 10 mm dimensions make these bearings suitable for compact spindle and rotary assemblies where space and precision matter. Main features and specifications Model: H7201C (7201) Quantity: 1 pair (matched set) Type: Angular contact bearing, spindle bearing Size: 12 mm (inner diameter) x 32 mm (outer diameter) x 10 mm (width) Seal: 2RZ (sealed both sides) Precision class: P4 Arrangement: DBA (backtoback), supplied as a matched pair for correct pairing and preload Functionality and compatibility Intended for use where combined radial and axial loads occur and where accurate axial location is required. Fits housings and shafts designed for a 12 mm bore and 32 mm outer diameter. Supplied as a matched backtoback set to simplify assembly into preloaded spindle arrangements and to ensure consistent bearing pair behavior. Typical applications CNC and router spindles: Provides the precision and axial support required for machining and routing at elevated speeds. speed motor and tool spindles: Ideal for rotary tools, grinders, and small precision motors where low runout and contamination resistance are critical. Precision instruments and laboratory equipment: Suitable for assemblies that demand stable rotation and long service life in compact spaces. Installation and handling notes Install the pair in the intended DBA (backtoback) orientation to achieve correct axial load distribution. Ensure clean mounting surfaces and correct shaft/housing fits to preserve precision and service life. Observe manufacturer recommendations for preload and lubrication compatible with sealed bearings; the 2RZ seals are designed to retain factory lubrication but check if relubrication is required for your duty cycle. Why choose this bearing pair This H7201C matched pair combines P4 precision, sealed construction, and a backtoback arrangement to deliver dependable, lowvibration performance in compact spindle applications. The sealed, matched set reduces assembly uncertainty and helps protect the bearing system from contaminants, making it a practical choice for precision rotating equipment.
