German FORMAT bearings FORMAT models FORMAT prices

FORMAT bearings are a type of rolling bearing and one of the widely used components in modern machinery. They support rotating parts through rolling contact between main elements. Roller bearings are now largely standardized. Roller bearings offer advantages such as low starting torque, high rotational accuracy, and ease of selection. Rolling bearings are classified into ball bearings and roller bearings based on the rolling element. Roller bearings support rotating parts through rolling contact between main components. Different roller bearings can withstand different radial and axial loads. When selecting roller bearings, the choice should be made according to specific operating conditions. Main structural types of roller bearings include spherical roller bearings, thrust spherical roller bearings, tapered roller bearings, and cylindrical roller bearings.

FORMAT bearing introduction

Linear bearings are linear motion systems used in conjunction with linear strokes and cylindrical shafts. Since the load-bearing balls have point contact with the bearing outer sleeve, the steel balls roll with minimal friction resistance. Therefore, linear bearings feature low friction, high stability unaffected by bearing speed, and enable smooth linear motion with high sensitivity and precision. Linear bearings have limitations, primarily poor impact load capacity and lower load-carrying capacity; secondly, they generate significant vibration and noise during high-speed motion. Automated selection of linear bearings is included. Linear bearings are widely applied in sliding components of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery. Due to the point contact between the load-bearing balls and the bearing, the permissible load is small. The steel balls rotate with extremely low friction resistance, thereby achieving high-precision smooth motion. Plastic linear bearings are self-lubricating linear motion systems. The biggest difference from metal linear bearings is that metal linear bearings operate on rolling friction with point contact between the bearing and the cylindrical shaft, making them suitable for low-load, high-speed motion; whereas plastic linear bearings operate on sliding friction with surface contact between the bearing and the cylindrical shaft, making them suitable for high-load, medium-to-low-speed motion.

FORMAT bearing features

Linear bearings are used in conjunction with hardened linear drive shafts as systems for infinite linear motion. Because the load-bearing balls and the hardened drive shaft have point contact, the permissible load is small, but during linear motion, friction resistance is minimal, precision is high, and movement is fast. Plastic linear bearings have no special requirements for the mating shaft; they can withstand greater loads than metal bearings, but since the motion between the bearing and the shaft is sliding friction, the speed of plastic linear bearings is somewhat limited; motion resistance is higher than that of metal linear bearings; however, their motion noise is lower than that of metal linear bearings, especially at medium-to-high speeds, where the noise of plastic linear bearings is minimally affected by speed. Due to the internal chip removal groove design, plastic linear bearings allow use in dusty environments, as dust is automatically carried out from the bearing friction surface through the grooves during motion; plastic linear bearings also allow cleaning during use, and internal sliding films made of special materials can even operate in liquids for extended periods.

FORMAT bearing maintenance

Maintenance of metal linear bearings: Lubrication and friction: Anti-corrosion oil is injected into the interior of linear bearings. If using grease lubrication, first remove the anti-corrosion oil with kerosene or an organic solvent, air dry, and then add lithium soap-based grease. (It is recommended to use lithium soap-based grease with a viscosity mark of N0.2.) If using oil lubrication, there is no need to remove the anti-corrosion oil; select lubricating oil with ISO viscosity grade VG15-100 according to temperature changes. Shaft lubrication can be supplied via an oil supply pipe or through oil holes on the external bearing housing. Since seals scrape off lubricating oil, oil lubrication is not suitable for sealed bearings without oil holes. Maintenance of plastic linear bearings: Since the sliding film inside plastic linear bearings is made of self-lubricating plastic, no additional oil supply or maintenance is required during use; moreover, because plastic linear bearings have chip removal grooves, no maintenance is needed even if the bearing or shaft is clogged with dust, as dust is automatically carried out through the grooves during motion; only when the sliding film wears out and fails is it necessary to replace the internal sliding film directly; maintenance is very convenient.
