Scaheffler’s INA linear technology is a newly-developed, six-row linear recirculating ball bearing and guide way assembly that are highly precise assemblies that run extremely soundlessly, which work efficiently in a measuring machine and well-established products.
The infeed zones in linear recirculating ball bearing and guide way assemblies, that is to say the area in which the rolling elements are conducted into the load carrying element until the load is fully applied is a critical factor for the life-limited mechanisms. They guarantee that the load is not suddenly applied to the rolling element yet progressively conducted. By refining the infeed zone design on the carriage saddle plates, INA Linear Technology has now accomplished in increasing the load ratings. The six-row KUSE linear recirculating ball bearing and guide way assemblies increased up to 44%, depending on the size and design. Due to the major increase in performance, the redesigned KUSE series has been awarded the Schaffler X-life quality mark. Six-row linear recirculating ball bearing and guide way assemblies have a high level of firmness and extremely low pulse amplitude (83%). They can be used in functions that tolerate slight pulsations and require high precision.
The recirculating rolling elements generally prevent a continuous amount of fully loaded rolling elements present in the load zone of the carriages at once. Depending on effectiveness within in the rolling elements during the load zone, the carriage balances deflections along the stroke to varying degrees causing a slight pulsing balancing movement in the load direction of the carriage. This particular movement is called stroke pulsation. Pulse amplitudes of up to 1 micrometer are not uncommon for a single ball. For the new KUSE X-life, the outline of the infeed zone has been improved so that the stroke pulsation is reduced, especially at higher loads.
KUSE X-life linear recirculating ball bearing and guide way assemblies are the highest in firmness and load carrying capacities based on balls currently on the market. Six rows, rather than the usual four, of balls support the loads. This particular arrangement of ball rows makes KUSE X-life designs perfect for combined load directions. KUSE X-life six-row linear recirculating ball bearing and guide way assemblies are appropriate for high-precision applications in electronics production, mold production, microscopy, optics, applications with high load carrying capacity, and operating performance. Here at ASAP Semi we like things to be improved so we have reasons for why customers need the newer version. We like our customers to have the updated version of any part being used on their vehicle.
