Overview
The NICE 1641DCTN is a precision-ground deep groove ball bearing from the 1600 Series, designed for reliable radial load applications in industrial machinery and equipment. This single-row bearing features double rubber seals (2RS) on both sides, protecting the rolling elements from contamination while maintaining smooth operation. With its compact 1″ bore and 2″ outer diameter, the 1641DCTN is ideal for moderate-speed, medium-load applications across automation, conveyors, pumps, and machine tool applications.
Key Features
- Precision Ground Design: All surfaces and ball grooves are precision ground for smooth rotation and minimal vibration
- Double Sealed Closure: Rubber seals on both sides protect against dust, moisture, and contaminants
- Non-Fill Slot Configuration: Ball retainer reduces ball-to-ball friction, enabling higher speed operation within rated limits
- 52100 Bearing Steel Construction: Premium bearing-grade steel provides uniform hardness and extended service life through controlled heat treatment
- Wide Temperature Range: Operates reliably from -40°F to +284°F, suitable for diverse industrial environments
