Ready-to-install ball lead screw support bearings

INA and FAG provide you with simpler and more economical ready-to-install ball lead screw support bearings, making the application of electromechanical drive systems for machine tool drive shafts more convenient.

The product range of FAG 7602, 7603 and BSB series bearings has become increasingly perfect, and they can be paired in groups for various specific working situations.

INA ZKLN and ZKLF series products can ensure reliable support for ball guide screws in a small space without the need for complex peripheral structures. This series of products with seals are widely favored by customers in the global market due to their high installation accuracy and rigidity, low friction and high torsional strength.

The DKLFA series is specially developed for positioning arrangement ball lead screw drives. This bearing is ideal where pretension is required to compensate for thermal expansion of the ball lead screw. The rolling elements in the third row can withstand continuously increasing unidirectional axial tension.

In addition, DKLFA series bearings are also very suitable for vertically arranged machine tool spindles under heavy loads. The outer ring is level on both sides and has a small cross-sectional height. This type of bearing also meets the requirements of installation and use.

High speed precision spindle bearing

Over the years, FAG spindle bearings have become the industry standard for reliability, precision and ultra-high speed.

The new TX spindle bearings are setting new standards as the cage design of the bearings has been optimized compared to previous spindle bearings. The new TX spindle bearing reduces the temperature rise by 10% during operation. At the same time, this new bearing series has the potential to increase the speed by 10% under the same boundary conditions.

B7 series spindle bearings have a very small tolerance range and are suitable for high-precision guidance and high-speed guidance. It has proven to be very suitable for machine tool spindle bearing design.

Excellent performance turntable bearings

Rotary table bearings for production machinery are among the Schaeffler Group's most complex specialty products in the industrial sector.

YRT series thrust radial cylindrical roller bearings

No. 1 in the world in turntable standard applications. Practical applications have proven that the bearing has reliable performance, high precision and high efficiency.

YRTS series thrust radial cylindrical roller bearings

The limit speed is seven times that of the previous standard design, with extremely low and stable friction torque, and the overturning rigidity is greatly improved. The reduction in friction results in lower bearing temperatures, which has a positive effect on the accuracy of the entire machine. This is why YRTS is an ideal bearing for direct drive turntable devices with high dynamic acceleration, allowing the potential performance of direct drives to be fully utilized. These bearings can optionally be equipped with a rotary encoder (YTRSM). The electronic measuring device works in conjunction with the IDAM direct drive to achieve extremely high performance. Damping connections between system parts and surrounding structures can effectively reduce vibrations from machining, and the measurement system is integrated with the bearings, thus saving additional assembly time.

ZKLDF series angular contact thrust ball bearings

Suitable for applications with very high rotational speeds, axial and radial forces, and long working hours. These axial angular contact ball bearings have a contact angle of 60°, low internal friction, are ready to install and are filled with grease. It provides high reliability and accuracy when operating with mixed loads.

The RTC series can meet the required runout accuracy such as rotary tables, face plates and milling heads.
