Nook Industries, a leading innovator of linear motion components and systems, introduces caged ball profile rails for linear guidance.
Caged ball chains provide reduced friction and lower noise levels and prevent the bearings from making incidental contact. An industry leader for more than 40 years, Nook’s new line improves on more traditional designs with lubrication advantages, a patented reinforcement plate and an overall dustproof design.
The lubrication design adds no additional length to the runner block and the pad contacts directly with the ball bearings. The lubrication storage pad can save enough lubricant to ensure long-term effects while conforming to environmental protection needs and lowering overall maintenance costs. Lubrication port fittings can be placed on the top, bottom or sides of the runner block, and O-ring seals ensure easy and clean lubrication.
The addition of two stainless steel reinforcement plates on either end of the runner block increases rigidity while adding a scraper function. With a clearance of less than 0.3 mm, the plate can remove items such as iron filings from the rail and also increases x-axis force capacity and operating speed.
Dustproof construction is accomplished through the plate design and several other advances. Newly designed inner seals slant inward at 45 degrees, protecting against foreign objects and reducing friction. A full-sealing bottom seal reduces oil usage by preventing lubrication leaks. Two different end-seal designs, Standard (B) and Reinforcement (S), allow customers to choose the solution best suited to their conditions.
“We feel that the addition of this line to Nook’s linear guidance solutions provides us with an even more complete solution for our customers,” said Ron Giovannone, project manager at Nook Industries. “It shows the creativity of our engineers, and an unmatched responsiveness to our customers’ needs.”
