- For travel up to 5,000 km without relubrication
- Roller runner block only needs initial lubrication with grease
- Front lube units on both sides of the roller runner block
- Low lubricant loss
Features
- Reduced oil consumption
- No lubrication lines
- Front lube unit can be refilled using the lube nipple on the end-face or at the side.
- Size 25: Lube connection on the end-face of the front lube unit is suitable for the grease lubrication of the Roller Runner Block. For this purpose, a lube pin is attached. For a detailed instruction for mounting with size 25, please refer to the Roller Rail System instruction.
Product description
Lubricant distribution
Due to the special lubricant distribution construction, lubrication occurs primarily where it is needed: directly on the running tracks and the top surfaces of the roller guide rails.
1 Top surfaces of the roller guide rails
2 Running tracks of the roller rail system
3 Oil tank
4 Front seals

Mounting
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).
Maximum tightening torque MA
| Size | Pos. 3  | Tightening torque MA in Nm |
| 25 | M3 x 15 | 0,7 |
| 35 | M3 x 22 | 0,7 |
| 45 | M4 x 25 | 1,0 |
| 55 | M5 x 30 | 1,3 |
| 65 | M4 x 30 | 1,0 |
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.
Maintenance
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 3 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).
