***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth END BLOCK FIXED B. CKK-12-90 (R037230005) is a high-precision compact module that integrates a ball rail system with a ball screw drive for dynamic and efficient linear motion. This compact unit is designed with a flat construction, optimizing the width to height ratio, which makes it ideal for applications where space is limited but high power density is required. The END BLOCK FIXED B. CKK-12-90 features a variety of structural components, including a zero-backlash single nut on the ball screw drive, cross ties, and an integrated carriage with runner blocks. A cover plate and reinforced PU belt cover strip protect the internal mechanisms, ensuring durability and longevity of the system. For motor attachment, this module provides options for both flanged type coupling and timing belt side drive, offering flexibility in integration with different motor types. The carriage also includes connection plates for additional attachments such as magnetic sensors and mounting ducts. An important aspect of this product is its lubrication versatility. It comes in different lubrication versions—LSS and LPG for manual grease lubrication, LCF for fluid grease central lubrication systems, and LCO for oil central lubrication systems—catering to various maintenance preferences. The END BLOCK FIXED B. CKK-12-90 boasts properties like high-speed capabilities over lengths up to 8,500 mm while maintaining precision. It has elastomer buffers that cushion the impact between carriage and screw supports. The screw supports are maintenance-free and shielded by the coverings to prevent sagging. However, it's crucial to note that the screw support is intended solely for horizontal operation. Additionally, this module features enhanced protection against contaminants through its resist cover design which includes FKM sealing profiles suitable for harsh environments such as those with aluminum chips or welding applications. Overall, the Bosch Rexroth END BLOCK FIXED B. CKK-12-90 offers a robust solution for linear motion requirements in compact spaces without compromising on speed or precision.

Additional component/actuation

A mounting duct is needed to fasten the sensors and cable guides. This is suspended at the side in a slot at the Compact Module and secured with set screws (4).

The set screws are included.

The sensors are pushed into the upper T-slot (CKK/CKR-090,-110 and CKK-145) or into the lower T-slot (CKR-145, CKK/CKR-200) of the mounting duct and secured with set screws.

Switch activation is done by magnets in the carriage.

Socket - plug

Notes:

Socket and plug are not wired.

This allows optimal assignment of switching positions during start-up.

One plug is included.

The plug can be installed in three directions.

For further information, see the "Socket - plug” view.

CKK/CKR-200

Magnetic sensor with plug

1 Sensor

2 Switch mounting plate including set screws (loose) and square nut 2a

3 Cable holder including set screw (loose)

Attachment/actuation

A switch mounting plate (2) is required to attach the sensors. This is suspended in the upper slot on the Compact Module and secured with set screws (4).

The sensors are pushed into the respective slot on the switch mounting plate and secured with one set screw.

The square nut with set screw (2a) serves as a positive stop for the sensor (switching position when changing sensors). Parts are included with the sensor mounting kit.

Switch activation is done by magnets in the carriage.

Overview

5 Cable duct

Alternatively, the connection line of the switches can also be attached by cable holder.

Additional component/actuation

The switches are suspended in the upper slot on the Compact Module and secured with set screws (4).

The actuation is done using switching cams (4). This is attached with the screws to the connection plate. Fastening screws are included.

Cable duct

The additional component is done in the lateral slots of the frame. Fastening screws widen the profile and give the cable duct a secure hold.

The cable duct will accommodate up to two cables for mechanical switches and three cables for proximity switches.

Fastening screws are included.
