Where it runs.
You will find Boston Gear reducers in the parts of a plant where this particular duty actually occurs. In practice that means package conveyors, food-processing lines, mixers, and equally indexing tables, small hoists, agitators. What links them is the duty rather than the machine name — type: Right-angle worm. 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 Regal Rexnord range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Washdown / Food & Beverage — SS700 stainless or stainless-shaft variant Standardized economy sizing — Tigear-2 die-cast worm reducer Overhung load at output — 700 Series steel output shaft for OHL capacity 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.
700 Series ships pre-lubricated for life; verify the mounting-position code at order since output hand and shaft side are fixed at build. Send the designation off the failed part and we will confirm the Regal Rexnord equivalent and stock position.
