bearings
Zhaofei Technology provides high-performance bearings, including ready-to-use ball screw support bearings, high-speed precision spindle bearings, and high-performance rotary table bearings. These bearings are widely used in mechanical equipment and are characterized by durability and precision. We are committed to meeting customer needs, providing customized solutions, and promoting industry development together with superior quality and professional service.
Ready-to-use ball screw support bearing

INA and FAG offer you simpler and more economical ready-to-use ball screw support bearings, making it easier to use in electromechanical drive systems for machine tool drive shafts.
The FAG 7602, 7603 and BSB series bearings have become increasingly comprehensive, and they can be paired together for various specific working conditions.
INA's ZKLN and ZKLF series products ensure reliable support for ball screws even in confined spaces without the need for complex peripheral structures. The sealed series, due to its high installation accuracy and rigidity, low friction, and high torsional strength, has gained widespread popularity among customers worldwide.
The DKLFA series is specially designed for positioning ball screw drives. It is ideal for applications requiring pre-tensioning to compensate for the thermal expansion of the ball screw. The rolling elements in the third row can withstand continuously increasing unidirectional axial tensile forces.
Furthermore, the DKLFA series bearings are also well-suited for vertically arranged machine tool spindles under heavy loads. The outer ring is horizontal on both sides and has a very small cross-sectional height. These bearings also meet the requirements for immediate use.

High-speed precision spindle bearings

For many years, FAG spindle bearings have been the industry standard in terms of reliability, precision, and ultra-high speed.
The new TX spindle bearings are setting a new standard, featuring an optimized cage design compared to previous models. The new TX spindle bearings reduce temperature rise by 10% during operation. Simultaneously, this new bearing series has the potential to increase rotational speed by 10% under the same boundary conditions.
The B7 series spindle bearings have a very small tolerance range, making them suitable for high-precision and high-speed guiding applications. They have proven to be very suitable for machine tool spindle bearing design.

High-performance turntable bearings

Turntable bearings used in production machinery are among the most complex specialty products in the Schaeffler Group's industrial sector.
YRT series thrust radial cylindrical roller bearings
It is the world's leading manufacturer in standard rotary table applications. Practical applications have proven that this bearing is reliable, highly precise, and highly efficient.
YRTS series thrust radial cylindrical roller bearings
The limiting speed is seven times that of the previous standard design, with extremely low and stable frictional torque, and significantly improved overturning rigidity. Reduced friction lowers bearing temperature, which positively impacts the overall precision of the machine. This is precisely why the YRTS is an ideal bearing for direct-drive rotary tables with high dynamic acceleration, allowing the full potential of direct drive to be realized. A rotary encoder (YTRSM) can be optionally configured in these bearings. Electronic measuring devices working in conjunction with the IDAM direct drive achieve extremely high performance. Damped connections between system components and the surrounding structure effectively reduce vibrations from machining, and the integration of the measuring system with the bearings saves additional assembly time.
ZKLDF series angular contact thrust ball bearings
Suitable for applications involving very high speeds, axial and radial forces, and long-term operation. These thrust angular contact ball bearings have a 60° contact angle, low internal friction, are ready to use, and are pre-lubricated. They offer high reliability and accuracy under mixed load conditions.
The RTC series can meet the runout accuracy requirements of components such as rotary tables, dials, and milling heads.
