The Bosch Rexroth LUBRICATING UNIT 25 (R181022500) is a sophisticated front lube unit designed specifically for roller rail systems, ensuring optimal lubrication and maintenance of the RSHP roller runner blocks and the latest generation of roller runner blocks. This unit facilitates a travel distance of up to 20,000 km without the need for relubrication, significantly reducing downtime and maintenance efforts. The product is engineered to require only initial greasing of the Roller Runner Block, with front lube units positioned on both sides to minimize lubricant loss and oil consumption. The R181022500 model boasts an efficient lubricant distribution construction that targets lubrication directly onto the running tracks and top surfaces of the roller guide rails, promoting consistent performance and longevity of the system. It also features an oil tank and front seals that contribute to its reduced oil consumption capabilities. The front lube unit can be easily refilled through a lube nipple located on its endface or side, adding convenience for users. With a maximum operating temperature range from -10°C to +80°C, it is suitable for various environmental conditions. The unit comes in size H for profiled rail systems and has been designed with a nominal size that ensures compatibility with different sizes of profiled rail systems including sizes B, E, N, A, as well as H profiled rail systems. It allows for easy installation and maintenance with a tightening torque specification of 2.5 Nm. Additionally, the LUBRICATING UNIT 25 weighs approximately 0.1 kg which makes it lightweight yet durable enough to withstand rigorous applications. This product is an essential accessory for profiled rail systems requiring reliable lubrication solutions that support long service intervals and consistent operation in industrial linear guide applications.

Prior to assembling the front lube units, an initial lubrication of the roller runner blocks with grease lubricant is required! See Roller Rail Systems - General technical notes and information, chapter "Maintenance".
Assembly of front lube units
The coated screws required for attachment additional end seals are supplied along with the unit.
In each case, mount a front lube unit (1) on both sides of the roller runner block! Do not remove the roller runner block from the rail! Slide on the front lube units (1) and end seals (2) and align them on the roller runner block. Tighten screws (3) with tightening torque MA (see table).

Notes
The coated screws required for attachment on the roller runner block, additional end seals and lube nipples are supplied along with the unit. The front lube units are already filled with oil (Mobil SHC 639) and can be mounted immediately after basic lubrication of the roller runner blocks.
Lubrication intervals for roller runner blocks with front lube units
Check the front lube units once the travel distance as specified in Figure (see below) is attained.Upon reaching the travel distance - or after no more than 2 years - we recommend replacing the front lube units and re-lubricating the roller runner block prior to assembly of the new front lube unit. In clean operating conditions, the roller runner blocks (sizes 35 to 65 on the side and size 25 at the front) can be re-lubricated with grease (Dynalub 510) (see table "Re-lubrication in cm3").
Attention:
If other lubricants are used, this may lead to a reduction in the lubrication intervals, the achievable travel in short-stroke applications, and the load capacities. Possible chemical interactions between the plastic materials, lubricants and preservative oils must also be taken into account. The recommended lubrication intervals depend on environmental factors, load and load type. Examples of environmental factors include swarf, mineral abrasion (or similar), solvent and temperature. Examples of load and load type are oscillations, shocks and tilting. The operating conditions are not known to the manufacturer. Only the user's own attempts or accurate monitoring can yield safety over the lubrication intervals. No water-based coolant/lubricant on the roller guide rails and roller runner block!

Load-dependent lubrication intervals for roller runner block with front lube units, size 25 to 65
This applies to the following conditions:
Roller runner block lubricants: Dynalub 510 (grease NLGI 2) or alternatively Castrol Longtime PD 2 (grease NLGI 2) Front lube units lubricant: Mobil SHC 639 (synthetic oil) Maximum speed: vmax = 2 m/s No media pressurization Standard seals Ambient temperature: T = 10 – 40°C
Note
The load ratio F/C is the quotient of the equivalent dynamic load on bearing F (making allowance for the preload for C2 or C3) divided by the dynamic load capacity C (see “Roller Rail Systems – General technical notes and information,” section “Technical data,” general technical data and calculations).
