A new dimension of safety to bolt security with the launch of the Nord-Lock X-series washer, says the company. The X-series combines the company’s Nord-Lock’s wedge-locking protection against spontaneous bolt loosening (due to vibration and dynamic loads) with an exclusive spring effect that protects against slackening due to settlement and relaxation. This combination makes X-series the first, true multifunctional design— offering the highest security for critical joints, without compromise.
New tech bring new demands
With new technologies and demands, joints increasingly must withstand stresses from multiple fronts, including vibration, dynamic loads, settlement, and relaxation. Yet, no solutions on the market have previously been designed to secure bolts from all of these at once. This has left designers with the difficulty of figuring out which issue — spontaneous bolt loosening or slackening — will have the biggest effect on the joint, and choosing a solution to handle that single problem. Nord-Lock says its X-series ensures total bolt security while simplifying design and maintenance since there is no need to use and stock multiple solutions.
How it works
As with Nord-Lock’s original washers, each pair has cams on one side and radial teeth on the opposite side to secure the bolted joint with tension instead of friction. The X-series washers’ conical shape also creates an elastic reserve in the bolted joint to compensate for the loss of preload and prevent slackening.
