Bijur Delimon – Meter Unit FJB-2: Medium Fast Flow, Junction Type B
L. Dewitt's SKU #: B2497 | Mfr Part #: B2497The Bijur Delimon B2497 Meter Unit (Type FJB-2) is a precision oil proportioning device for Single Line Resistance (SLR) cyclic lubrication systems. The FJB is the most commonly used meter unit junction type — it threads into a standard Bijur junction or junction header and delivers "Medium Fast" metered oil via a 5/32" tail tube to the bearing point.
Regulated Medium Fast Flow
As a FJB-2 model, this unit delivers Medium Fast flow, designed for larger or more heavily loaded bearings that require a more generous oil supply per cycle. Typical candidates include loaded spindle bearings, large linear slides, and higher-speed shafts where under-lubrication leads to accelerated wear.
Cyclic System Integrity
An integrated 5 lb check valve ensures one-directional oil flow (arrow stamped on 3/8" hex body) and prevents the tail tube and distribution lines from draining back during the pump's off cycle. For cyclic lubrication systems only. Not compatible with continuous-flow pumps.
