Premium F695ZZ/695ZZ Bearings

NSK 695 Series Precision Bearings – Premium Bearings

Designed for high-performance DIY 3D printers, both bearings feature ZZ1 double metal shields that protect the bearing from dust while retaining the factory lubrication. Metal shields generate less drag than contact seals, making these bearings an excellent choice for high-speed idlers, belt tensioners, guide rollers and other precision motion components.

NSK 695ZZ1MC3 PS2S

This bearing is factory-filled with MULTEMP PS No.2 premium synthetic grease. Developed for precision bearings, it delivers very low running torque while maintaining excellent lubrication across a wide operating temperature range of -50°C to +110°C. This makes it ideal for printers operating in cold workshops as well as enclosed machines where elevated temperatures are common.

Additional specifications include:

• MC3 standard NSK internal clearance for smooth running and reliable performance.
• PS2 premium MULTEMP PS No.2 synthetic grease for low torque and excellent low-temperature performance.
• S increased grease fill for extended lubrication life and reduced maintenance.

NSK 695ZZ1MC2ERP5 J NS7KM

This premium precision version is designed for applications where extremely smooth, quiet and accurate operation is required. It is lubricated with NS HI-LUBE (NS7), a premium synthetic grease developed for wide temperature operation, low torque and reduced running noise.

NS HI-LUBE offers an operating temperature range of -40°C to +130°C, providing excellent thermal stability for enclosed printers and other demanding applications. Its low-friction formulation helps maintain smooth motion while minimizing bearing noise.

Additional premium specifications include:

• MC2 internal clearance for tighter running clearance than MC3.
• ER extra-low noise specification.
• P5 precision manufacturing tolerance for improved running accuracy.
• J pressed steel ribbon cage.
• M increased grease fill for extended lubrication life.
