OG exemplary drawing
 
1. A split plummer block bearing housing for a rotatable shaft, comprising:
a detachable housing cap having at least one housing grease channel, and
at least one seal assembly,
wherein the at least one seal assembly comprises:
a stationary part mounted on the housing cap, and having a seal grease channel,
a rotating part configured to be mounted on the shaft, and
a seal body in a seal chamber defined by the stationary part and the rotating part,
wherein the stationary part and the rotating part are configured to cooperate with each other as a labyrinth and/or contacting seal,
wherein the housing grease channel and the seal grease channel connect and form an extension of each other,
wherein the housing grease channel extends radially and linearly from a radial exterior side of the housing cap to a radially inner surface of the housing cap, and
wherein the seal grease channel extends radially and linearly from a radial outer surface of the stationary part to the seal chamber.
 
9. A split plummer block bearing housing for a rotatable shaft, comprising:
a detachable housing cap having at least one housing grease channel, and
at least one seal assembly,
wherein the at least one seal assembly comprises:
a stationary part having a seal grease channel,
a rotating part configured to be mounted on the shaft, and
a seal body in a seal chamber defined by the stationary part and the rotating part,
wherein the housing cap is mounted to a radially outer portion of the stationary part such that a joint is formed between the housing cap and the stationary part,
wherein the stationary part and the rotating part cooperate with each to form a labyrinth seal,
wherein the housing grease channel includes a radial outer end at a radially exterior side of the housing cap and a radial inner end,
wherein the seal grease channel includes a radial outer end facing the radial inner end of the housing grease channel,
wherein the seal grease channel is in fluid communication with the housing grease channel and forms an extension of the housing grease channel,
wherein the housing grease channel extends linearly from the radial exterior side of the housing cap to a radially interior side of the housing cap, and
wherein the seal grease channel extends linearly from a radial outer surface of the stationary part to the seal chamber.
