Compression spring
Frequently Asked Questions
Q: What is the PR 201266 compression spring used for in electric lift truck chargers?
A: The PR 201266 is a compression spring that provides contact force in battery charger connector blocks. It maintains pressure between the movable and stationary contact tips, ensuring consistent electrical contact and allowing the connector to mate and separate smoothly without jamming or incomplete seating.
Q: What are the specifications of the PR 201266 and how do I verify correct replacement?
A: Verify the spring constant in pounds per inch (lbs/in), free length, compressed length, and material grade. These springs are typically stainless steel or music wire to resist corrosion from moisture and salt exposure in warehouse environments. Always match the spring rate to the original specification; incorrect spring tension causes poor contact or connector damage.
Q: What causes compression springs like the PR 201266 to fail and how long do they last?
A: Springs fail due to corrosion, fatigue from repeated compression cycles, or deformation from exposure to extreme temperatures. Under normal use, compression springs last 5 to 10 years. Signs of failure include reduced spring tension, visible rust or pitting, or contact tips not seating fully in the connector block.
Q: Is the PR 201266 spring compatible with all Crown, Toyota, and Raymond charger models?
A: No. Spring specifications vary by connector block model and contact tip diameter. Verify the connector block part number and contact pin configuration before ordering. Using an incorrect spring rate results in loose connections, arcing, or mechanical binding that prevents proper mating.
