Lubricant Metering Devices
The devices that divide one pump output into measured doses for individual bearings: progressive divider blocks, single-line injectors and dual-line distributors. The metering principle you choose decides how the system behaves when a point blocks. SES holds the range as an authorised SKF distributor, covering types Progressive dividers, single-line injectors, dual-line distributors; dose per outlet Fractions of a cubic centimetre upward, per cycle; outlets per unit Typically six to twenty, expandable by sections; materials Steel and stainless steel bodies. Executions include progressive divider blocks, sectional, progressive divider blocks, single-piece body, single-line injectors, adjustable, dual-line distributors, among others. It is specified most often into crusher, screen and feeder bearing groups and conveyor pulley and idler point banks. Every part is genuine SKF through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Lubricant Metering Devices in the parts of a plant where this particular duty actually occurs. In practice that means crusher, screen and feeder bearing groups, conveyor pulley and idler point banks, rolling mill stand and chock lubrication points, and equally press shop tooling and slide lubrication, kiln support roller and thrust roller assemblies, excavator, shovel and crane pin and bush points. What links them is the duty rather than the machine name — principles: Progressive, single-line injector, dual-line. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the SKF range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. You must know that one specific bearing received its dose — A progressive block with a cycle indicator pin or proximity switch on it. Progressive pistons move in a fixed sequence, so a stopped pin is direct evidence rather than an inference from pump pressure. Point doses that need trimming after commissioning — Adjustable single-line injectors. Changing a dose on a progressive block means changing the metering section, which is a workshop job rather than a screwdriver adjustment. Several hundred points across a large machine or a long line — Dual-line distributors fed from a reversing valve. Progressive systems of that size become a nest of blocks where a single blockage silently starves an entire branch. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
A progressive block stops completely when one outlet blocks, and that is deliberate. Put the indicator on the block feeding the bearing you least want to lose, because that is the one whose stall you want reported first.
