Seal washer

Seal washer

Expect vibration damping and noise reduction effects! It demonstrates sufficient performance even when used directly on the surfaces of black steel and cast iron.

We handle "seal washers." This is a set product that incorporates a rubber packing into a metal-drawn bowl-shaped washer. The rubber packing is press-fitted onto the threaded part of the bolt, sealing the fluid at the side. The design minimizes rubber overflow even when tightened to the appropriate torque. We use SUS304, which is resistant to rust, as the standard material. 【Features】 ■ Suitable for preventing gas and liquid leakage ■ Passed pressure tests up to 200 atmospheres (20 MPa) ■ Demonstrates sufficient performance even when used directly on the surface of black steel and cast iron ■ Vibration damping and noise reduction effects ■ The metal and rubber packing do not resonate with vibrations *For more details, please refer to the PDF materials or feel free to contact us.

Slack Prevention Bolt, Nut, Washer 'ActiveX'

Slack Prevention Bolt, Nut, Washer 'ActiveX'

Achieves a skirt shape that does not sag. It is reusable and can also reduce costs.

"ActiveX" is a bolt, nut, and washer that realizes high anti-loosening functionality with a simple shape, based on the concept of "absorbing the force that loosens screws." The spring effect generated by the elastic deformation of the skirt section absorbs vibrations and shocks, demonstrating its anti-loosening effect. According to the NAS3350 standard, vibration tests were conducted using JQA's high-speed screw loosening testing machine, resulting in a finding that it does not loosen for 17 minutes. 【Features】 ■ The spring effect generated by the elastic deformation of the skirt section absorbs vibrations and shocks. ■ Special shape for full contact of the seating surface. ■ Excellent reusability, allowing for cost reduction. ■ Passed vibration tests under the NAS3350 standard for 30,000 cycles (17 minutes). *For more details, please refer to the PDF document or feel free to contact us.
