3 Woodworking Machines

Long Life even with Wood Chip Contamination

Life is 2 times longer than standard double seals in Running test in wood chips

Comparison test between NSK K1 and standard double seal

Test conditions

Sample: LH30AN (Preload Z1)

Feed rate: 20 m/min

Stroke: 400 mm

Lubrication: Standard double seal - AV2 grease

NSK K1 - NSK K1 + AV2 grease

Load: 490 N per one ball slide

Wood chip contamination: Set the product in the box with bottom area A, then

put 240 g of wood chips on the rails. Put back removed wood

chips to rails 3 times/day.

[High volume of chips]: A = 145 mm (width) × 700 mm (length)

[Medium volume of chips]: A = 170 mm (width) × 700 mm (length)
