Support unit?

The KOSA support unit is a precision unit product that is standardized to firmly support the ball screw or slide screw for straight motion. The fixed side support unit and the support side support unit are prepared.

Features of Support Units

Compact

The compact construction reduces assembly space and pre-pressurized bearings allow for assembly to be assembled in such a state to reduce the number of assembly workers and improve assembly precision.

High Precision

The precision combination of angular bearings (contact angle 30 °, DF-front combination) is designed to absorb parallel errors in the guide and the rotation axis to the center of the shaft, minimizing adverse effects of assembly errors and maintaining precision of the rotation axis.

Special

Standardized products are highly compatible, and specialized according to customer needs and usage. Please inquire in advance about material change, surface processing change, and design change depending on customer application.

Application and Use of Support Units

Application of precision grinding ball screw

- Assembly Robot - Light Equipment - Three-dimensional measuring instruments - Transfer machines other than semiconductor and LCD inspection equipment

Application of the pre-boll screw

- Industrial Robo-Steel Equipment Machinery - Polished Machine - Transport Machine other than Printing Machine

TM Screws and Deliverables

Medical machine, microscope X-Y axis, etc.

Guitar

A machine that requires less play in the axial direction of the machine.

Structure of Support Units

The fixed side support unit is composed of high-rigidity, low-torque angular bearings (30 ° contact angle, DF-front combination) suitable for the dynamic characteristics of the rotating axis, and can achieve high precision rotational performance through precise preload. The support side support unit uses deep groove bearings and the support unit is filled with an adequate amount of gurice and oil seals are assembled to prevent the ingress of fine dust or foreign substances for prolonged use.

Configuration and classification of support units

There are two types of rigid structures that secure support units to the base surface and a circular (flen-surface) type that fits into a hole. The product must be selected according to the conditions of use and installation. It consists of fixed support unI and support support units on the opposite side of the fixed side, depending on the location of the power transfer shaft.
