Description
The Nord-Lock X-Series washers with enlarged outer diameter (SP) combine Nord-Lock wedge-locking with an innovative spring effect, offering the highest security against spontaneous bolt loosening and slackening.
This product is the optimum choice when you have both vibrations and applications with risk of slackening such as short clamp length, multiple clamped parts, gaskets, soft metals, plastic composites, coatings and thermal cycling.
Nord-Lock X-Series washers have been rigorously tested and approved by independent institutes as well as certification authorities.
Advantages
SP Washers
Nord-Lock washers are available in two outer diameters — standard and enlarged. Washers with an enlarged outer diameter (SP washers) are designed to be used together with flanged bolts and nuts (ISO 4161,4162) on oversized and slotted holes, or on sensitive surfaces and soft materials.
This product is the optimum choice when you have both vibrations and applications with risk of slackening such as short clamp length, multiple clamped parts, gaskets, soft metals, plastic composites, coatings and thermal cycling.
Nord-Lock X-Series washers have been rigorously tested and approved by independent institutes as well as certification authorities.
Advantages
- Prevents bolt loosening caused by vibration and dynamic loads
- Compensates for loss of preload due to settlement and relaxation
- Accurate preload with defined and uniform friction
- Reusable, depending on conditions of use
- Quick and easy assembly and disassembly
- Increases operational reliability while reducing the risk of unplanned production stops, accidents, and warranty claims
- High corrosion resistance, tested minimum 1,000 hours in the Neutral Salt Spray Test
- One solution to cover multiple design challenges
