Condition Assisted Lubrication (CAL)
A single-point or multi-point lubricator whose dosing is driven by measured bearing condition rather than a fixed calendar interval. A sensor watches the bearing, and grease is released only when the signal shows the film is thinning. SES holds the range as an authorised SKF distributor, covering sensor input Vibration or acoustic emission from the bearing housing; dosing Electromechanical or gas-driven single-point lubricator; cartridge life Months, depending on dose frequency and cartridge size; output signal Volt-free alarm contact or plant network message. Executions include single-point condition assisted lubricators, multi-point systems with a shared controller, battery-powered wireless units, hardwired units with plant network output. It is specified most often into ID and FD fan bearings on boilers and kilns and motor drive-end bearings in inaccessible cable galleries. 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.

Prevents
Both starvation and seal damage from over-greasing
Where it runs.
You will find Condition Assisted Lubrication (CAL) in the parts of a plant where this particular duty actually occurs. In practice that means ID and FD fan bearings on boilers and kilns, motor drive-end bearings in inaccessible cable galleries, conveyor drive pulley bearings on long overland routes, and equally process pump bearing housings in continuous plants, cooling tower fan gearboxes and shaft bearings. What links them is the duty rather than the machine name — trigger: Measured bearing signal, not a timer. 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. Bearing point that greasers cannot reach safely while running — An automatic unit with condition feedback and a remote alarm contact. The alternative is a fixed interval that nobody can verify, which is how housings end up packed solid. Duty that swings between idle and full load through the week — Condition-driven dosing rather than running hours. Hour-based schedules over-grease during light weeks and starve the bearing during a campaign run. Bearing already showing a rising envelope trend — Diagnose before you fit anything. A spalled raceway will keep calling for grease and the extra dose only quietens the signal while the damage continues to spread. 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.
Record a clean baseline over at least one full production cycle before you let the unit dose on its own. Without that reference the system is reacting to whatever the machine happened to be doing on commissioning day.
